When I mention the word Anabantoid, I'm sure the first
thing that comes to most Aquarist's minds is the group of fishes we
know as Gouramis. Some of you might even think of the Siamese Fighting
Fish. The name "Bubblenesters' might also come to mind. By the
end of this program, I hope you all will be a bit broader minded when
it comes to Anabantoids, and might even be encouraged to try your hand
at keeping and maybe even breeding some of these wonderful animals.
Let me begin by saying that the following are from my
own experiences and research working with and learning about the Anabantoids
over the past 3 decades. It's in no way meant to be a scientific treatise,
and I don't want to argue the finer points of what is or is not a valid
scientific name. I'm stating everything in general terms to make things
easier for the audience. This is a hobbyist work presented by a hobbyist
to other hobbyists. There are as many ways to do things in this hobby
as there are hobbyists. None of them are wrong, and most of them are
at least somewhat "right". This is only the way I do things,
it works for me. It may or may not work for you. Remember, too, that
fish don't read books or listen to talks! : )
I promise I won't get too technical, but some basic
science is in order to define the group of animals we'll be talking
about. Taxonomically speaking Anabantoids are a suborder of the Order,
or group of fishes, collectively known as the Perciformes, or Perch-like
fishes. This means they are cousins of the Perch, the Darters, the Cichlids,
and the Badids, among others. They are found only in Sub-Saharan Africa
and Southeast Asia from India to as far north as the Korean peninsula.
In addition to various anatomical similarities, nearly all of these
fishes practice some form of brood care. We'll come back to that
a bit later.
One of the main things that separate the Anabantoids from
other Perciformes is the presence of an accessory breathing organ, known
as the Labyrinth. Thus the Anabantoids are often referred to as "Labyrinth
Fish". This organ is a modification of the bone structure behind
the gills, covered by a vast network of thin capillaries. It allows
the fish to gulp atmospheric air, extract oxygen and release carbon
dioxide directly to the air. The Anabantoids have become so dependent
on this ability that many species will actually drown if denied access
to the air!
One interesting myth that has grown in the aquarium lore
about this organ is that the fry must have warm, humid air above the
water surface while the labyrinth organ is developing or they will develop
pneumonia and die. No one is sure exactly where this myth originated,
but it is often repeated in the literature from the 1950's onward.
Many scientific studies have been done that have disproved this myth.
Countless hobbyists have raised Betta splendens spawns at room
temperature with no special provision for the protection of the fry.
I have had Paradise fish spawn outdoors in November (in a heated tub
pond kept at 65 degrees) and they successfully raised several hundred
fry. Nighttime air temperatures often dipped into the low 30's
before I moved them indoors. I also had a pair of Trichopsis schalleri
(one of the Croaking Gouramis) spawn in a tank that had an occasional
current of air from the air conditioner blow across the surface. I raised
nearly 200 fry from that spawn in that tank with no problems. Simply
stated: This myth is not true!
The Labyrinth organ allows Anabantoids to take advantage
of habitats that would be inaccessible to fish that cannot utilize atmospheric
oxygen due to the low dissolved oxygen content of the water. They are
often found in swamps, roadside ditches, rice paddies, shallow ponds,
puddles and even in damp leaf litter on the forest floor! Larger species
are often stocked into rice paddies along with the rice, and are harvested
right along with the rice at the end of the growing season.
Larger species are prized as food and are often found
in market stalls crammed into jars, buckets, or even wrapped in wet
leaves - still very much alive! While this may seem cruel in our eyes,
they form an important source of protein in the local diet, and have
been brought to market in this same way for thousands of years. The
fishes' ability to live under these conditions is a testament to their
hardiness! They can be kept in buckets, tubs or jars until the family
is ready to cook them, and so provide a fresh, safe source of meat for
the family diet. It may be the only safe meat they get. Anyone who has
visited the other meat vendors' stalls in an open-air market can attest
to the questionable quality of the meats that are offered (not to mention
the flies and the stench!). Fresh fish is a welcome change!
Now that we know a little about the fish, let's
discuss their needs in captivity.
Anabantoids will do well in most commercially available
tanks and can live out their entire lives, even spawning and raising
a brood of fry in that same tank. Even though they will survive
in small aquaria, don't keep them in small, cramped tanks. Give them
room to exhibit their natural behavior, and gear the size of the tank
to the adult size of the fish. Smaller Anabantoids can be kept in tanks
as small as 5 -; 10 gallons, with medium sized Anabantoids doing better
in 20 – 30 gallon tanks. Medium to large Anabantoids should be
kept in 55 – 75 gallon tanks, and truly giant species should really
be kept in super tanks or indoor ponds. Planted tanks are best, with
some floating plants to provide security and a place for the bubble
nest builders to build their nests. Most Anabantoids can be kept in
community tanks, and are often the "star attraction" of such
tanks with their bright colors and "friendly" behavior toward
the hobbyist. Just make sure that the fishes in the community are similar
in size, or the Anabantoids will take advantage of your generosity and
eat the live food that you provided for them!
Most Anabantoids do well in small groups, generally with
one male and a few females. Males of many species will scrap amongst
themselves, but if enough room is given, little harm will be done. If
there isn't enough room, you might find that one dominant fish kills
all of the other fish of their sex in the tank. With enough room, you'll
see behavior similar to what happens in the wild. The dominant fish
will threaten the other fish, which will take on submissive coloration
and behavior and move off with no harm done. No matter the size of the
tank, I try to provide several "caves" made from flowerpots
laid on their sides or pieces of PVC pipe – with openings facing
in different directions. My rule of thumb is to have more "caves"
than there are fish, so every fish feels comfortable and has a place
to rush to hide if it feels threatened.
Anabantoids are GENERALLY warm water fish that do best
with water temperatures close to 80 degrees Fahrenheit. There are some
notable exceptions, which I'll mention below when I talk about the individual
groups of fish. Most species will do just fine at normal tropical fish
maintenance temperatures of 76- 78 degrees Fahrenheit, though they will
need warmer water if you want them to breed.
Feeding Anabantoids is not a problem. Even wild caught
fish of most species will take flake foods within a few days. Standard
size pellet foods work well as a staple diet for larger species, while
micro pellets will work for all but a few species. Don't feed
them a diet of the same foods every day, though. Mix it up to give them
variety and provide them with all of the nutrients they need. Many Gouramis,
especially the Trichogaster species and the Kissers, like to have some
vegetable matter in their diets. I give them Spirulina based flakes,
and they love Duckweed (Lemna sp.) too. Most Anabantoids love meaty
foods, and will eat frozen and freeze dried foods with gusto. I thaw
and rinse frozen foods in a separate container before feeding the tank.
Others just drop the frozen chunks right into the tank and let them
thaw in there as the fish pick at them. Both methods work equally well.
If you can provide them with an occasional meal of live
foods, so much the better. Live worms make excellent foods for Anabantoids.
Make sure you size the worms to the fish, though! Even a small fish
will try to tackle a large worm, but it would be better to offer them
a bite-sized meal! I feed live black worms to my fish at least once
or twice a week. Smaller fish like Licorice Gouramis will get Grindal
Worms, while larger fish like some of the Bushfish will get Red Worms.
Pinhead crickets are also great food for medium sized Anabantoids like
the Trichogaster species, and the larger Kissing Gouramis and True Gouramis
greedily eat larger crickets and mealworms. Only the Pike Gouramis of
the genus Luciocephalus seem to require live fish on a regular
basis. Make sure the feeder fish are healthy and free of disease, and
feed them well before feeding them to the Pikes.
There is no one "best" filter for an Anabantoid
tank. Any type of filter will work just fine with the Anabantoids, though
there are a few things to keep in mind when you are setting up your
system. Gear your filter to the type of fish you want to keep. First
of all, you'll want to remember that many Anabantoids are large-bodied
fish and will produce a larger amount of waste than a thinner bodied
fish of similar length. Secondly, many Anabantoids need a calm surface
area to spawn, so you'll want at least a certain amount of the surface
to be turbulence free. You'll also want to remember that most (though
not all) Anabantoids don't like the strong current of many power filters.
Undergravel filters often inhibit live plant growth. And sponge and
box filters provide a lot of turbulence at the surface. Canister filters
are often the filter of choice for planted tanks, and will serve you
well in a nice planted community tank stocked with Anabantoids and other
fish, but they are expensive to buy – often costing as much as
the rest of the system combined! So what is a hobbyist to do?
Use whatever filter you will be able to easily and regularly
maintain. Every hobbyist will have his or her own preference that develops
over time as they build experience. Most of us have several old filters
we don't use anymore for one reason or another. Just remember
that if you won't maintain it or it's too difficult to maintain,
even the most expensive filter will rapidly become useless to your fish.
Personally, I use sponge filters. I cover the surface with Water Sprite
so that a large area is calm. I rinse the sponges once every other week,
and rotate airstones every couple of months.
As for water, most of the water sources in the US are
local rivers, springs or impoundments. Generally, with the exception
of folks who have "liquid rock", the water is fine for keeping
fish IF it's fit to drink. Even "liquid rock" is fine
for keeping fish, but won't work if you want to get them to breed.
If you are unlucky enough to have liquid rock, I can emphasize with
you. I had it for several years. I was still successful with breeding
soft water fish, but it was a lot more work.
Let's talk about water parameters in general. This
is often the most controversial thing that I mention when I do a talk
on fish. We are often told to monitor and even change pH, ammonia, hardness,
etc., but are not told why or what these parameters mean. We often hear
you have to keep this fish in soft, acid water or that one in hard,
alkaline water, but what does that really mean? And how do you do it?
Very few hobbyists are chemists, and even fewer actually understand
what playing around with all of these parameters can do in an aquarium.
Let me preface this by saying I've been keeping
and breeding fish since the early 1970's, and have done so in
different homes with very different water parameters and have had vastly
different levels of success depending on methods that I've used.
I've not just worked with and bred a few varieties of fish, either,
but with over 150 species from about 20 families just in the last dozen
or so years since I've been active in my club's Breeder's
Award Program, and many more before that. Many of those (70+ species)
have been Tetras, Rasboras, Anabantoids, and other fish that are considered
"difficult" to breed, so I do have some basis for what I'm
about to say. I'm not trying to brag, but to let you know that
I do know what I'm talking about and can prove it by what I've
been able to do with it. I've also talked to a lot of other successful
long-time hobbyists over the years, and have found most of them agree
with this philosophy, too. You'll not find it in too many books
nor will you hear about it in most shops – I'm not sure
exactly why. I have developed this basic philosophy: let the fish adapt
to your water, don't try to adapt your water to the fish.
Why do I speak this "heresy"? Because nearly
all freshwater fishes are remarkably adaptable animals. In the wild,
a fish might experience a temperature fluctuation of more than 20 degrees
in a short time when their hot riverside puddle is suddenly flushed
with torrential rainwater. In a similar way they might also experience
a sudden change in hardness, salinity or pH. This might stun them or
stress them temporarily, but a healthy fish won't suffer long
term harm from these changes. In many species, these very changes are
the trigger for spawning! In addition, many species are found in several
streams separated by many miles and flowing over vastly different terrain.
Most areas in the Tropics are subject to huge seasonal fluctuations
in water parameters. In Southeast Asia, where many of our most popular
Anabantoids come from, they might be found in an acid water swamp in
one area, and a few miles away might be in a hard water limestone pond.
With a few exceptions, they can't just get up and leave the water
they find themselves in, they have to adapt. In general, fishes that
are found in the softest, most acid water in the wild are the most adaptable,
while those found in harder, more alkaline water are less adaptable,
and those found in marine water are the least adaptable of all.
Again without getting too scientific, the main reason
fish can't take changes in captivity is due to the fact that stresses
due to crowding and poor water quality have weakened them. Dissolved
organic matter (uneaten food, waste products, rotting plant matter,
etc.) combines with the "end product" of bacterial activity
(nitrate) and slowly poisons the fish. The water may be perfectly clear,
but testing would show a high dissolved solids content, a slowly dropping
pH, and a nitrate reading that is off the scale. THAT is the reason
for frequent testing. When you start to see these changes, you should
change the water. The water would appear yellow to the eye. I have seen
some tanks that were reading over 500 ppm of nitrate AFTER a 50% water
change with tap water that had no nitrate content! This often is the
opening that many disease organisms need to take advantage of the fish
and make them ill. This weakens the fish further, then, when there finally
is a change in water parameters, the further stress placed on the fish
kills it. But if you are doing regular filter maintenance and regular
large water changes you won't need to monitor water parameters.
Test when you first set up the tank so you know what your
water parameters are. Test the water parameters of new fish so you know
how long to let them adapt to your water, and slowly drip your water
(in your quarantine tank) into their bag or bucket. Remember that changes
from harder to softer water are more stressful on the fish and should
be done more slowly, and you'll be fine. Also remember, the reagents
in test kits degrade over time. If you have old test kits, throw them
away.
If you stock lightly and do regular water changes with
your own tap water, you will limit the stress placed on the fish by
poor water quality and crowding. pH and hardness would be of secondary
importance. If you were not trying to get the fish to breed, they would
be totally unimportant. One key to success, not only with Anabantoids,
but also with all fish, is to do large, regular water changes. Since
you are not having to monkey with the water parameters first, you will
be more apt to do regular water changes instead of just doing them when
the fish are visibly distressed – when it's often too late!
Anyway, the point of all of this is to say that with a
few exceptions for breeding, most Anabantoids will do just fine in your
local tap water for their entire lives. I know, it's a long way
to make a short point, but I thought I should go through my reasoning
as to why I'm saying it. : )
Now, let's talk about the fish.
First, let's briefly cover the groups of Anabantoids
that hobbyists are less likely to encounter.
First there is the Anabantidae, with the genera
Anabas (the Climbing Perch), Ctenopoma and Microctenopoma
(the Bushfish). These are generally heavy-bodied large predatory fish
that are not too often seen in aquaria. The Anabas and Ctenopoma
are generally considered food fishes in their native lands. Most are
large, and are various shades of brown and gray. They eat anything that
will fit in their mouths. Some are a bit scrappy with other fish in
their tanks, while others ignore anything that won't fit in their
mouths. They are rarely kept in aquaria, and are not much sought after
except by advanced hobbyists looking for a challenge. Most will not
reach maturity for a couple to several years. Mature fish will spawn
readily, often when a storm front comes through. The eggs of most species
float, and no nest is made. Fry are able to eat newly hatched brine
shrimp once they are free swimming. Anabas species are banned
in many southern States due to their prolific nature and their much
overblown ability to move from one water body to another by "walking"
with spines in their gill covers.
The Microctenopoma are often found in aquaria.
They are generally smaller versions of the Ctenopoma, and some
scientists still lump them into Ctenopoma. Some are attractively
patterned, and most do well in standard community tanks. They prefer
meaty foods and love frozen bloodworms. They are "hidden spawners",
with the male building a small bubble nest in some hidden nook, often
in a cave. Fry are generally small and need infusoria for a few days
before they can take baby brine shrimp.
Next, we find the Belontiidae, the Combtail Gouramis
of the genus Belontia. These are rarely found in aquaria, though
they are often very attractive. The males and females often display
bright rust to orange coloration with metallic blue highlights, and
the unpaired fins sport long extensions. The extensions on the tail
look like the teeth of a comb, hence the common name. Sadly, these beautiful
fish grow up to 6" or so and are rather aggressive, both with
other Combtails and with other fish. In general, they need a large,
well-planted species tank to do their best. They might do well with
larger Barbs and Rasboras, and might possibly do well with some Cichlids,
but the other fish should be able to take care of themselves or have
enough room to swim away! They spawn at the surface, sometimes with
and sometimes without a nest. The eggs are free floating. The male often
takes the eggs into his mouth and moves them to another area. Fry can
be fed infusoria for a few days, then will take baby brine. Due to the
number of eggs (more than 5000), a large number of fry will be lost
to starvation unless a lot of food is present. It is best to remove
some of the eggs to another tank to hatch and feed and leave the rest
to their fate in the main tank.
The next group is the Helostomatidae, the Kissing
Gouramis of the genus Helostoma. These fish are often kept at
a small size for their interesting display of "kissing"
one another. This is a behavior that is little understood and endearing
to the hobbyist until he/she learns that their cute little Kisser will
quickly grow into a 10 – 12" monster, even in a small tank!
These are a popular food fish in their native land, and are often cultured
in ponds on small farms. Interestingly, they are fed pig droppings as
a staple diet, and they grow very quickly on this food (though I can't
imagine what this makes them taste like!). They take a few years to
reach maturity and require a large tank (6' or larger) to do well.
They lay up to 10,000 floating eggs and provide no parental care. The
fry need infusoria for a week or so, and will then do well and grow
quickly on live baby brine shrimp. Again, if you are lucky enough to
get them to spawn for you, remove a few eggs to raise in another tank,
and leave the rest to their fate. There is no point in trying to raise
that many fry!
Now we come to a rare and little kept group of predators,
Luciocephalidae, the Pike Gouramis. There is almost no information
on the husbandry of these 6 – 8" fish except that they are
piscivores – which means they eat fish! I have never seen them
for sale, and have only recently seen photos of living fish, so I won't
really comment on them further.
The last small group of Anabantoids is Osphronemidae,
the True or Giant Gouramis. These animals can live for 20 years or more
and reach a size of 30". They are considered an excellent food
animal. While they are often seen for sale at a size of 2 – 3",
I can't really recommend them for the average hobbyist's
tank. You would need at least a 300 to 1000 gallon tank or a good sized,
deep pond to give them a real home. Why keep an animal that you can't
provide a home for when it reaches maturity? Don't expect the
shop to take it back, another hobbyist to take it, or a local zoo or
public aquarium to take it either – they won't! I won't
comment further on this group of fishes, either.
Now we have the group of Anabantoids we are all most familiar
with: The Gouramis and the Bettas. They belong to the largest two sub-families
of Anabantoids, the Trichogasterinae and the Macropodinae,
respectively. Nearly all of the fish you will encounter in the hobby
will be in one of these two groups. There are enough species in these
two groups to keep even an advanced hobbyist busy for many years, yet
many of these fish are among those recommended for the beginner's
first tank! Many of them are very colorful. Some have been selectively
bred to many different color variants. Some are very easy to get to
breed, others are challenging even for advanced hobbyists with years
of experience. Some are very peaceful. Some are very aggressive amongst
themselves but do just great with other fishes, others make you wonder
how they even get together to breed in the wild they are so aggressive!
They exhibit fascinating breeding behavior. Some fishes
build large, elaborate nests, even weaving in plant leaves. Others build
tiny, hidden nests. Yet others build no nest at all. Still others are
paternal (the father carries the eggs) mouthbrooders. And still others
are maternal mouthbrooders. And finally, some species build nests sometimes,
are mouthbrooders other times, and are generally confusing to everyone!
Some species have even yet to be bred by hobbyists, and even today some
have not yet been available in the hobby!
First we have the Gouramis: Trichogaster (Three
spot and it's color variants, Snakeskin, Moonlight, and Pearl);
Colisa (Dwarf, Honey, Thicklip, and "Giant" or Banded),
Parasphaerichthys (False Chocolate) and Spaerichthys (4
species of Chocolate Gouramis).
Trichogaster Gouramis all grow fairly large (4
– 8") and are a bit scrappy when full-grown. They will do
well in community tanks of appropriate sized fish. They build large
bubble nests and lay many eggs. 1000 or more is not uncommon for an
adult female. The fry need infusoria for a week or more then will take
live baby brine shrimp or vinegar eels.
Colisa Gouramis are small to medium sized fish
(1-1/2" to 3") that are peaceful and do well in community
tanks. Mature males will scrap amongst themselves, so it's best
to keep just one male to a tank. They build HUGE nests, up to nearly
a foot across and a couple inches high, and weave bits of plant matter
into the structure. The nest may last long after the fry have moved
on. Some males will spawn with more than one female in the same nest.
Fry hatch in about 12 hours, and are very small when first free swimming.
They need green water for a few days, then infusoria for a week up to
two weeks, and then live baby brine.
Paraspaerichthys Gouramis are very uncommon in
the hobby. I have only seen them once. Some reports have them being
a mouth brooder, others have them building a small nest. I don't
know, I've never had breeding success with them.
Sphaerichthys Gouramis are seldom seen for sale.
There is somewhat of a mystical quality about them. I could (and did,
TFH, November 2000) write a long article about them. I won't
go into detail here. These small (1-1/2" to 2-1/2") Gouramis
are reputed to be hard to keep, and I found that the case in the past.
But recently I have had much success with keeping them. They are maternal
mouthbrooders and once mature are fairly easy to induce to spawn. The
trick is to keep them long enough for them to reach maturity! In the
past, I followed the limited literature and kept them at pH of 4.0 –
5.0, 0 carbonates and a temperature of 90 degrees to get a spawning.
I found them to be VERY aggressive amongst themselves at this temperature,
and do not recommend these water parameters to anyone – the water
has no buffering capacity, biological activity is virtually nil in the
filter, and the water can crash very quickly. Recently, keeping them
in normal tap water (pH 7.0 – 7.2, total hardness of 125 ppm,
mostly from carbonates) and at a slightly elevated temperature (82 degrees)
was enough to induce them to successfully spawn – with much less
aggression!
Now we move to the largest grouping of Anabantoids, the
Macropodinae. They are all elongated fish with torpedo-like bodies.
This group includes the Bettas (40 – 60 species, depending
on the author); Ctenops (1 species); Macropodus (4 or 5 species);
Malpulutta (1 species); Parosphromenus (a dozen or so
species); Pseudosphronemus (2 species) and Trichopsis
(3 or more species).
Ctenops is the Noble Gourami. It is rarely seen
in the hobby, and can be a bit touchy if kept in "dirty"
water. I have not had success with spawning them yet, and have heard
that they are a mouthbrooder. I can't verify that, though.
Macropodus is the group of Paradisefish. These
are mostly temperate water fishes found as far north as the Korean peninsula
that can take very cool water temperatures. They are somewhat aggressive,
though can easily be kept with most common community fishes. Males are
more colorful than females and have longer and more fin extensions,
but both males and females are beautiful and well worth the fuss –
just don't keep them with Angels or fancy guppies and you'll
not have any trouble. They spawn easily, and produce many fry. Some
fry can take live baby brine as a first food, but you are better off
at least starting them with infusoria for a few days first.
Malpulutta kretseri is a beautiful, very, very
rare fish found only on Sri Lanka, where it is endangered due to habitat
destruction. It is easy to spawn, and produces a few dozen fry that
will take infusoria for a few days and then live baby brine shrimp.
One problem is that spawns are frequently nearly all one sex or the
other. While probably temperature related, I don't know for sure.
Parosphronemus are the Licorice Gouramis. I'm
not sure why the earned this moniker! It might have something to do
with the black stripes on them, but I don't know for sure. What
I do know is that they are beautiful. These tiny fish often come in
with Velvet infections and losses are high unless they are treated right
away. This gives them the reputation of being very delicate, but that
is not true. It also causes the prices to be uncommonly high! Once the
Velvet is gone, they are very hardy and long-lived. They do require
very small live foods as most of them don't reach an inch when
full grown! They do best in small groups in species tanks. I prefer
to feed them Grindal worms and live baby brine shrimp. I have had some
take micro pellets, but most ignore anything that isn't moving.
They seem to do better in cooler water, and I have had breeding success
only in aquaria that were in the low to mid 70's. They spend a
lot of time hiding in the plants, and build a secret nest under the
leaves of plants or in a cave. A dozen to 20 fry would be a good spawn.
The fry will take infusoria for a few days, followed by live baby brine.
Most of the time, though, by the time you notice the fry they are already
eating the same food as the adults. Due to the small brood size, they
have found enough micro fauna to graze on for the first few days! The
parents don't seem to be too interested in the fry, and they can
be raised in the tank with the adults.
Pseudosphronemus are the Spiketail Gouramis. They
are similar to the Licorice Gouramis in behavior and care, but grow
larger (to 2") and can be kept in community tanks. Spawns of 50
– 70 are common, and fry are large enough for live baby brine.
Trichopsis are the Croaking Gouramis. There are
two, three or more species, depending on what authority you consult.
They are all smallish, and one species (the Pygmy or Sparkling Gourami)
can be considered one of if not the smallest species of Gourami. They
all build secretive nests below the surface, taking advantage of whatever
decoration might suit their needs. Spawns of 20 are common, though the
largest species, The Croaking Gourami, can lay more than 100 eggs. Fry
need infusoria for a week or so, then baby brine.
Finally we come to the largest single genera – the
Bettas. Incidentally, I'll throw in on the side that it
is pronounced Bet – tuh, not BAY-TA. Sorry, but it's a pet
peeve of mine. The name is derived from a local Thai name for one of
the species – Ikan bettah; not BETA, which is the
second letter of the Greek alphabet. My two cents.
Anyway, when you hear the name Betta you might
instantly think of the Siamese Fighting Fish, but that is only one of
up to 60 species. Interestingly, most of the known species of Betta
are not nest builders, but rather are mouth brooders! There are so many
different species that hobbyists have divided them into several species
groups to make it easier to understand their varied needs. Many species
are small, but some Bettas can reach up to 6' or so! They are
found all over, from lowland swamps to mountain streams, and many species
are found in only a small area -perhaps only a single stream. Some species
spend their entire lives hiding in the leaf litter, while others spend
their time in open waters. Some build large bubble nests, while others
build very small nests. The females of the mouthbrooding species are
often more aggressive than the males, and multiple brooding males can
be seen hiding in the same cave! All of the eggs that I have seen so
far, from both small and large species, both bubble nesters and mouthbrooders,
look very similar! They remind me of small, flat whitish balls, like
a basketball without any air in it. And they are all about the same
size. I'm not saying this is so for all species, but I found it an interesting
similarity in the 15 or so species I've seen spawn so far.
Also, in general, the mouthbrooders seem to prefer cooler
water than the nest builders. I've had them spawn in water that
was in the upper 60's, and stop spawning at all in water that
was more "Betta like" in the low 80's. Young mouthbrooders
also seem to generally be much larger and able to take baby brine shrimp
upon release, while most young bubble nesters need at least a few days
of infusoria before they are ready to take baby brine. However, some
domestic Betta splendens strains will take baby brine as a first food.
And that brings us to the end of this "talk"
on Anabantoids. I hope you might want to learn more. There are many
excellent books out there on the group, though most are long out of
print. Some of the best that you can easily find still in print are
Bettas by Bob Goldstein which covers many of the species in the
genus in detail, and Gouramis and Other Labyrinth Fishes by Gary
Elson and Oliver Lucanus. Both are published by Barrons and are available
through most bookstores.
I know I covered a lot in a short time. Are there any
questions?

- [20:05 09/07/2004] <@craig> Good evening everyone,
welcome to this weeks Live! Fishchat!
- [20:05 09/07/2004] <@craig> Tonights speaker is Mike
Hellweg, his topic: Anabantoids.
- [20:05 09/07/2004] <@craig> Mike, when ever you are
ready, take it away!
- [20:06 09/07/2004] <+Mike> Okay. This is basically
the same talk I've given to a half dozen or so clubs over
the years - you guys just don't get the slide show.
- [20:06 09/07/2004] <+Mike> When I mention the word
Anabantoid, I'm sure the first thing that comes to most Aquarist's
minds is the group of fishes we know as Gouramis. Some of
you might even think of the Siamese Fighting Fish. The name
'Bubblenesters' might also come to mind. By the end of this
program, I hope you all will be a bit broader minded when
it comes to Anabantoids, and might even be encouraged to try
your hand at keeping and maybe even breeding some o
- [20:13 09/07/2004] <+Mike> The Labyrinth organ allows
Anabantoids to take advantage of habitats that would be inaccessible
to fish that cannot utilize atmospheric oxygen due to the
low dissolved oxygen content of the water. They are often
found in swamps, roadside ditches, rice paddies, shallow ponds,
puddles and even in damp leaf litter on the forest floor!
Larger species are often stocked into rice paddies along with
the rice, and are harvested right along with the rice at the
- [20:14 09/07/2004] <+Mike> Larger species are prized
as food and are often found in market stalls crammed into
jars, buckets, or even wrapped in wet leaves - still very
much alive! While this may seem cruel in our eyes, they form
an important source of protein in the local diet, and have
been brought to market in this same way for thousands of years.
The fishes' ability to live under these conditions is a testament
to their hardiness!
- [20:14 09/07/2004] <+Mike> Larger species are prized

been brought to market in this same way for thousands of years.
The fishes' ability to live under these conditions is a testament
to their hardiness!
- [20:15 09/07/2004] <+Mike> Now that we know a little
about the fish, let's discuss their needs in captivity.
- [20:15 09/07/2004] <+Mike> Anabantoids will do well
in most commercially available tanks and can live out their
entire lives, even spawning and raising a brood of fry in
that same tank. Even though they will survive in small aquaria,
don't keep them in small, cramped tanks. Give them room to
exhibit their natural behavior, and gear the size of the tank
to the adult size of the fish.
- [20:16 09/07/2004] <+Mike> Smaller Anabantoids can
be kept in tanks as small as 5 - 10 gallons, with medium sized
Anabantoids doing better in 20 - 30 gallon tanks. Medium to
large Anabantoids should be kept in 55 - 75 gallon tanks,
and truly giant species should really be kept in super tanks
or indoor ponds. Planted tanks are best, with some floating
plants to provide security and a place for the bubble nest
builders to build their nests.
- [20:17 09/07/2004] <+Mike> Most Anabantoids can be
kept in community tanks, and are often the 'star attraction'
of such tanks with their bright colors and 'friendly' behavior
toward the hobbyist. Just make sure that the fishes in the
community are similar in size, or the Anabantoids will take
advantage of your generosity and eat the live food that you
provided for them!
- [20:17 09/07/2004] <+Mike> Most Anabantoids do well
in small groups, generally with one male and a few females.
Males of many species will scrap amongst themselves, but if
enough room is given, little harm will be done. If there isn't
enough room, you might find that one dominant fish kills all
of the other fish of their sex in the tank. With enough room,
you'll see behavior similar to what happens in the wild
- [20:18 09/07/2004] <+Mike> The dominant fish will
threaten the other fish, which will take on submissive coloration
and behavior and move off with no harm done. No matter the
size of the tank, I try to provide several 'caves' made from
flowerpots laid on their sides or pieces of PVC pipe - with
openings facing in different directions. My rule of thumb
is to have more 'caves' than there are fish, so every fish
feels comfortable and has a place to rush to hide
- [20:19 09/07/2004] <+Mike> Anabantoids are GENERALLY
warm water fish that do best with water temperatures close
to 80 degrees Fahrenheit. There are some notable exceptions,
which I'll mention below when I talk about the individual
groups of fish. Most species will do just fine at normal tropical
fish maintenance temperatures of 76 - 78 degrees Fahrenheit,
though they will need warmer water if you want them to breed.
- [20:19 09/07/2004] <+Mike> Feeding Anabantoids is
not a problem. Even wild caught fish of most species will
take flake foods within a few days. Standard size pellet foods
work well as a staple diet for larger species, while micro
pellets will work for all but a few species. Don't feed them
a diet of the same foods every day, though. Mix it up to give
them variety and provide them with all of the nutrients they
need.
- [20:20 09/07/2004] <+Mike> If you can provide them
with an occasional meal of live foods, so much the better.
Live worms make excellent foods for Anabantoids. Make sure
you size the worms to the fish, though! Even a small fish
will try to tackle a large worm, but it would be better to
offer them a bite-sized meal! I feed live black worms to my
fish at least once or twice a week.
- [20:21 09/07/2004] <+Mike> Smaller fish like Licorice
Gouramis will get Grindal Worms, while larger fish like some
of the Bushfish will get Red Worms. Pinhead crickets are also
great food for medium sized Anabantoids like the Trichogaster
species, and the larger Kissing Gouramis and True Gouramis
greedily eat larger crickets and mealworms.
- [20:22 09/07/2004] <+Mike> Only the Pike Gouramis
of the genus Luciocephalus seem to require live fish on a
regular basis. Make sure the feeder fish are healthy and free
of disease, and feed them well before feeding them to the
Pikes.
- [20:22 09/07/2004] <+Mike> There is no one 'best'
filter for an Anabantoid tank. Any type of filter will work
just fine with the Anabantoids, though there are a few things
to keep in mind when you are setting up your system. Gear
your filter to the type of fish you want to keep.
- [20:23 09/07/2004] <+Mike> First of all, you'll want
to remember that many Anabantoids are large-bodied fish and
will produce a larger amount of waste than a thinner bodied
fish of similar length. Secondly, many Anabantoids need a
calm surface area to spawn, so you'll want at least a certain
amount of the surface to be turbulence free.
- [20:24 09/07/2004] <+Mike> Use whatever filter you
will be able to easily and regularly maintain. Every hobbyist
will have his or her own preference that develops over time
as they build experience. Most of us have several old filters
we don't use anymore for one reason or another. Just remember
that if you won't maintain it or it's too difficult to maintain,
even the most expensive filter will rapidly become useless
to your fish.
- [20:24 09/07/2004] <+Mike> Personally, I use sponge
filters. I cover the surface with Water Sprite so that a large
area is calm. I rinse the sponges once every other week, and
rotate airstones every couple of months.
- [20:25 09/07/2004] <+Mike> Let's talk about water
parameters in general. This is often the most controversial
thing that I mention when I do a talk on fish. We are often
told to monitor and even change pH, ammonia, hardness, etc.,
but are not told why or what these parameters mean. We often
hear you have to keep this fish in soft, acid water or that
one in hard, alkaline water, but what does that really mean?
And how do you do it?
- [20:26 09/07/2004] <+Mike> Very few hobbyists are
chemists, and even fewer actually understand what playing
around with all of these parameters can do in an aquarium.
- [20:27 09/07/2004] <+Mike> . Many of those (70+ species)
have been Tetras, Rasboras, Anabantoids, and other fish that
are considered 'difficult' to breed, so I do have some basis
for what I'm about to say. I'm not trying to brag, but to
let you know that I do know what I'm talking about and can
prove it by what I've been able to do with it.
- [20:27 09/07/2004] <+Mike> I've also talked to a lot
of other successful long-time hobbyists over the years, and
have found most of them agree with this philosophy, too. You'll
not find it in too many books nor will you hear about it in
most shops - I'm not sure exactly why.
- [20:28 09/07/2004] <+Mike> Okay, now that I've set
it up, here goes:
- [20:28 09/07/2004] <+Mike> I have developed this basic
philosophy: let the fish adapt to your water, don't try to
adapt your water to the fish.
- [20:28 09/07/2004] <+Mike> Why do I speak this 'heresy'?
- [20:29 09/07/2004] <+Mike> Because nearly all freshwater
fishes are remarkably adaptable animals. In the wild, a fish
might experience a temperature fluctuation of more than 20
degrees in a short time when their hot riverside puddle is
suddenly flushed with torrential rainwater.
- [20:29 09/07/2004] <+Mike> In a similar way they might
also experience a sudden change in hardness, salinity or pH.
This might stun them or stress them temporarily, but a healthy
fish won't suffer long term harm from these changes. In many
species, these very changes are the trigger for spawning!
- [20:30 09/07/2004] <+Mike> In addition, many species
are found in several streams separated by many miles and flowing
over vastly different terrain. Most areas in the Tropics are
subject to huge seasonal fluctuations in water parameters.
- [20:30 09/07/2004] <+Mike> In Southeast Asia, where
many of our most popular Anabantoids come from, they might
be found in an acid water swamp in one area, and a few miles
away might be in a hard water limestone pond. With a few exceptions,
they can't just get up and leave the water they find themselves
in, they have to adapt.
- [20:31 09/07/2004] <+Mike> In general, fishes that
are found in the softest, most acid water in the wild are
the most adaptable, while those found in harder, more alkaline
water are less adaptable, and those found in marine water
are the least adaptable of all.
- [20:31 09/07/2004] <+Mike> Again without getting too
scientific, the main reason fish can't take changes in captivity
is due to the fact that stresses due to crowding and poor
water quality have weakened them.
- [20:32 09/07/2004] <+Mike> Dissolved organic matter
(uneaten food, waste products, rotting plant matter, etc.)
combines with the 'end product' of bacterial activity (nitrate)
and slowly poisons the fish. The water may be perfectly clear,
but testing would show a high dissolved solids content, a
slowly dropping pH, and a nitrate reading that is off the
scale.
- [20:32 09/07/2004] <+Mike> THAT is the reason for
frequent testing. When you start to see these changes, you
should change the water. The water would appear yellow to
the eye. I have seen some tanks that were reading over 500
ppm of nitrate AFTER a 50% water change with tap water that
had no nitrate content!
- [20:33 09/07/2004] <+Mike> This often is the opening
that many disease organisms need to take advantage of the
fish and make them ill. This weakens the fish further, then,
when there finally is a change in water parameters, the further
stress placed on the fish kills it. But if you are doing regular
filter maintenance and regular large water changes you won't
need to monitor water parameters.
- [20:34 09/07/2004] <+Mike> If you stock lightly and
do regular water changes with your own tap water, you will
limit the stress placed on the fish by poor water quality
and crowding. pH and hardness would be of secondary importance.
If you were not trying to get the fish to breed, they would
be totally unimportant.
- [20:35 09/07/2004] <+Mike> One key to success, not
only with Anabantoids, but also with all fish, is to do large,
regular water changes. Since you are not having to monkey
with the water parameters first, you will be more apt to do
regular water changes instead of just doing them when the
fish are visibly distressed - when it's often too late!
- [20:35 09/07/2004] <+Mike> Anyway, the point of all
of this is to say that with a few exceptions for breeding,
most Anabantoids will do just fine in your local tap water
for their entire lives. I know, it's a long way to make a
short point, but I thought I should go through my reasoning
as to why I'm saying it. : )
- [20:35 09/07/2004] <+Mike> Now, let's talk about the
fish.
- [20:36 09/07/2004] <+Mike> First, let's briefly cover
the groups of Anabantoids that hobbyists are less likely to
encounter.
- [20:36 09/07/2004] <+Mike> First there is the Anabantidae,
with the genera Anabas (the Climbing Perch), Ctenopoma and
Microctenopoma (the Bushfish). These are generally heavy-bodied
large predatory fish that are not too often seen in aquaria.
The Anabas and Ctenopoma are generally considered food fishes
in their native lands. Most are large, and are various shades
of brown and gray.
- [20:37 09/07/2004] <+Mike> They eat anything that
will fit in their mouths. Some are a bit scrappy with other
fish in their tanks, while others ignore anything that won't
fit in their mouths. They are rarely kept in aquaria, and
are not much sought after except by advanced hobbyists looking
for a challenge.
- [20:37 09/07/2004] <+Mike> Most will not reach maturity
for a couple to several years. Mature fish will spawn readily,
often when a storm front comes through. The eggs of most species
float, and no nest is made. Fry are able to eat newly hatched
brine shrimp once they are free swimming.
- [20:37 09/07/2004] <+Mike> Anabas species are banned
in many southern States due to their prolific nature and their
much overblown ability to move from one water body to another
by 'walking' with spines in their gill covers.
- [20:38 09/07/2004] <+Mike> The Microctenopoma are
often found in aquaria. They are generally smaller versions
of the Ctenopoma, and some scientists still lump them into
Ctenopoma. Some are attractively patterned, and most do well
in standard community tanks.
- [20:39 09/07/2004] <+Mike> They prefer meaty foods
and love frozen bloodworms. They are 'hidden spawners', with
the male building a small bubble nest in some hidden nook,
often in a cave. Fry are generally small and need infusoria
for a few days before they can take baby brine shrimp.
- [20:39 09/07/2004] <+Mike> Next, we find the Belontiidae,
the Combtail Gouramis of the genus Belontia. These are rarely
found in aquaria, though they are often very attractive. The
males and females often display bright rust to orange coloration
with metallic blue highlights, and the unpaired fins sport
long extensions. The extensions on the tail look like the
teeth of a comb, hence the common name.
- [20:40 09/07/2004] <+Mike> Sadly, these beautiful
fish grow up to 6' or so and are rather aggressive, both with
other Combtails and with other fish. In general, they need
a large, well-planted species tank to do their best. They
might do well with larger Barbs and Rasboras, and might possibly
do well with some Cichlids, but the other fish should be able
to take care of themselves or have enough room to swim away!
- [20:41 09/07/2004] <+Mike> The next group is the Helostomatidae,
the Kissing Gouramis of the genus Helostoma. These fish are
often kept at a small size for their interesting display of
'kissing' one another. This is a behavior that is little understood
and endearing to the hobbyist until he/she learns that their
cute little Kisser will quickly grow into a 10 - 12' monster,
even in a small tank!
- [20:41 09/07/2004] <+Mike> These are a popular food
fish in their native land, and are often cultured in ponds
on small farms. Interestingly, they are fed pig droppings
as a staple diet, and they grow very quickly on this food
(though I can't imagine what this makes them taste like!).
- [20:42 09/07/2004] <+Mike> They take a few years to
reach maturity and require a large tank (6' or larger) to
do well. They lay up to 10,000 floating eggs and provide no
parental care. The fry need infusoria for a week or so, and
will then do well and grow quickly on live baby brine shrimp.
Again, if you are lucky enough to get them to spawn for you,
remove a few eggs to raise in another tank, and leave the
rest to their fate. There is no point in trying to raise that
many
- [20:43 09/07/2004] <+Mike> Now we come to a rare and
little kept group of predators, Luciocephalidae, the Pike
Gouramis. There is almost no information on the husbandry
of these 6 - 8' fish except that they are piscivores - which
means they eat fish! I have never seen them for sale, and
have only recently seen photos of living fish, so I won't
really comment on them further.
- [20:43 09/07/2004] <+Mike> The last small group of
Anabantoids is Osphronemidae, the True or Giant Gouramis.
These animals can live for 20 years or more and reach a size
of 30'. They are considered an excellent food animal. While
they are often seen for sale at a size of 2 - 3', I can't
really recommend them for the average hobbyist's tank. You
would need at least a 300 to 1000 gallon tank or a good sized,
deep pond to give them a real home.
- [20:44 09/07/2004] <+Mike> Why keep an animal that
you can't provide a home for when it reaches maturity? Don't
expect the shop to take it back, another hobbyist to take
it, or a local zoo or public aquarium to take it either -
they won't! I won't comment further on this group of fishes,
either.
- [20:44 09/07/2004] <+Mike> Now we have the group of
Anabantoids we are all most familiar with: The Gouramis and
the Bettas. They belong to the largest two sub-families of
Anabantoids, the Trichogasterinae and the Macropodinae, respectively.
Nearly all of the fish you will encounter in the hobby will
be in one of these two groups.
- [20:45 09/07/2004] <+Mike> There are enough species
in these two groups to keep even an advanced hobbyist busy
for many years, yet many of these fish are among those recommended
for the beginner's first tank! Many of them are very colorful.
Some have been selectively bred to many different color variants.
- [20:45 09/07/2004] <+Mike> Some are very easy to get
to breed, others are challenging even for advanced hobbyists
with years of experience. Some are very peaceful. Some are
very aggressive amongst themselves but do just great with
other fishes, others make you wonder how they even get together
to breed in the wild they are so aggressive!
- [20:46 09/07/2004] <+Mike> They exhibit fascinating
breeding behavior. Some fishes build large, elaborate nests,
even weaving in plant leaves. Others build tiny, hidden nests.
Yet others build no nest at all. Still others are paternal
(the father carries the eggs) mouthbrooders. And still others
are maternal mouthbrooders.
- [20:46 09/07/2004] <+Mike> And finally, some species
build nests sometimes, are mouthbrooders other times, and
are generally confusing to everyone! Some species have even
yet to be bred by hobbyists, and even today some have not
yet been available in the hobby!
- [20:47 09/07/2004] <+Mike> Now, lets look at each
group individually. I won't go into too much detail, just
enough to whet your appetites! : )
- [20:47 09/07/2004] <+Mike> First we have the Gouramis:
Trichogaster (Three spot and it's color variants, Snakeskin,
Moonlight, and Pearl); Colisa (Dwarf, Honey, Thicklip, and
'Giant' or Banded), Parasphaerichthys (False Chocolate) and
Spaerichthys (4 species of Chocolate Gouramis).
[20:48 09/07/2004] <+Mike> Trichogaster Gouramis all
grow fairly large (4 - 8') and are a bit scrappy when full-grown.
They will do well in community tanks of appropriate sized
fish. They build large bubble nests and lay many eggs. 1000
or more is not uncommon for an adult female. The fry need
infusoria for a week or more then will take live baby brine
shrimp or vinegar eels.
- [20:48 09/07/2004] <+Mike> Colisa Gouramis are small
to medium sized fish (1-1/2' to 3') that are peaceful and
do well in community tanks. Mature males will scrap amongst
themselves, so it's best to keep just one male to a tank.
They build HUGE nests, up to nearly a foot across and a couple
inches high, and weave bits of plant matter into the structure.
The nest may last long after the fry have moved on.
- [20:49 09/07/2004] <+Mike> Some males will spawn with
more than one female in the same nest. Fry hatch in about
12 hours, and are very small when first free swimming. They
need green water for a few days, then infusoria for a week
up to two weeks, and then live baby brine.
- [20:49 09/07/2004] <+Mike> Paraspaerichthys Gouramis
are very uncommon in the hobby. I have only seen them once.
Some reports have them being a mouth brooder, others have
them building a small nest. I don't know, I've never had breeding
success with them.
- [20:50 09/07/2004] <+Mike> Sphaerichthys Gouramis
are seldom seen for sale. There is somewhat of a mystical
quality about them. I could (and did, TFH, November 2000)
write a long article about them. I won't go into detail here.
These small (1-1/2' to 2-1/2') Gouramis are reputed to be
hard to keep, and I found that the case in the past. But recently
I have had much success with keeping them. They are maternal
mouthbrooders and once mature are fairly easy to induc
- [20:51 09/07/2004] <+Mike> The trick is to keep them
long enough for them to reach maturity! In the past, I followed
the limited literature and kept them at pH of 4.0 - 5.0, 0
carbonates and a temperature of 90 degrees to get a spawning.
I found them to be VERY aggressive amongst themselves at this
temperature, and do not recommend these water parameters to
anyone - the water has no buffering capacity, biological activity
is virtually nil in the filter, and the water can
- [20:51 09/07/2004] <+Mike> Recently, keeping them
in normal tap water (pH 7.0 - 7.2, total hardness of 125 ppm,
mostly from carbonates) and at a slightly elevated temperature
(82 degrees) was enough to induce them to successfully spawn
- with much less aggression!
- [20:51 09/07/2004] <+Mike> Now we move to the largest
grouping of Anabantoids, the Macropodinae. They are all elongated
fish with torpedo-like bodies. This group includes the Bettas
(40 - 60 species, depending on the author); Ctenops (1 species);
Macropodus (4 or 5 species); Malpulutta (1 species); Parosphromenus
(a dozen or so species); Pseudosphronemus (2 species) and
Trichopsis (3 or more species).
- [20:52 09/07/2004] <+Mike> Ctenops is the Noble Gourami.
It is rarely seen in the hobby, and can be a bit touchy if
kept in 'dirty' water. I have not had success with spawning
them yet, and have heard that they are a mouthbrooder. I can't
verify that, though.
- [20:52 09/07/2004] <+Mike> Macropodus is the group
of Paradisefish. These are mostly temperate water fishes found
as far north as the Korean peninsula that can take very cool
water temperatures. They are somewhat aggressive, though can
easily be kept with most common community fishes.
- [20:53 09/07/2004] <+Mike> Males are more colorful
than females and have longer and more fin extensions, but
both males and females are beautiful and well worth the fuss
- just don't keep them with Angels or fancy guppies and you'll
not have any trouble.
- [20:53 09/07/2004] <+Mike> They spawn easily, and
produce many fry. Some fry can take live baby brine as a first
food, but you are better off at least starting them with infusoria
for a few days first.
- [20:54 09/07/2004] <+Mike> Malpulutta kretseri is
a beautiful, very, very rare fish found only on Sri Lanka,
where it is endangered due to habitat destruction. It is easy
to spawn, and produces a few dozen fry that will take infusoria
for a few days and then live baby brine shrimp. One problem
is that spawns are frequently nearly all one sex or the other.
While probably temperature related, I don't know for sure.
I'm working with them now.
- [20:55 09/07/2004] <+Mike> Parosphronemus are the
Licorice Gouramis. I'm not sure why the earned this moniker!
It might have something to do with the black stripes on them,
but I don't know for sure. What I do know is that they are
beautiful.
- [20:55 09/07/2004] <+Mike> These tiny fish often come
in with Velvet infections and losses are high unless they
are treated right away. This gives them the reputation of
being very delicate, but that is not true. It also causes
the prices to be uncommonly high! Once the Velvet is gone,
they are very hardy and long-lived.
- [20:55 09/07/2004] <+Mike> They do require very small
live foods as most of them don't reach an inch when full grown!
They do best in small groups in species tanks. I prefer to
feed them Grindal worms and live baby brine shrimp. I have
had some take micro pellets, but most ignore anything that
isn't moving. They seem to do better in cooler water, and
I have had breeding success only in aquaria that were in the
low to mid 70's.
- [20:56 09/07/2004] <+Mike> They spend a lot of time
hiding in the plants, and build a secret nest under the leaves
of plants or in a cave. A dozen to 20 fry would be a good
spawn. The fry will take infusoria for a few days, followed
by live baby brine. Most of the time, though, by the time
you notice the fry they are already eating the same food as
the adults.
- [20:56 09/07/2004] <+Mike> Due to the small brood
size, they have found enough micro fauna to graze on for the
first few days! The parents don't seem to be too interested
in the fry, and they can be raised in the tank with the adults.
- [20:57 09/07/2004] <+Mike> Pseudosphronemus are the
Spiketail Gouramis. They are similar to the Licorice Gouramis
in behavior and care, but grow larger (to 2') and can be kept
in community tanks. Spawns of 50 - 70 are common, and fry
are large enough for live baby brine.
- [20:57 09/07/2004] <+Mike> Trichopsis are the Croaking
Gouramis. There are two, three or more species, depending
on what authority you consult. They are all smallish, and
one species (the Pygmy or Sparkling Gourami) can be considered
one of if not the smallest species of Gourami.
- [20:57 09/07/2004] <+Mike> They all build secretive
nests below the surface, taking advantage of whatever decoration
might suit their needs. Spawns of 20 are common, though the
largest species, The Croaking Gourami, can lay more than 100
eggs. Fry need infusoria for a week or so, then baby brine.
- [20:58 09/07/2004] <+Mike> Finally we come to the
largest single genera - the Bettas. Incidentally, I'll throw
in on the side that it is pronounced Bet - tuh, not BAY-TA.
Sorry, but it's a pet peeve of mine. The name is derived from
a local Thai name for one of the species - Ikan bettah; not
BETA, which is the second letter of the Greek alphabet. My
two cents.
- [20:58 09/07/2004] <+Mike> Anyway, when you hear the
name Betta you might instantly think of the Siamese Fighting
Fish, but that is only one of up to 60 species. Interestingly,
most of the known species of Betta are not nest builders,
but rather are mouth brooders! There are so many different
species that hobbyists have divided them into several species
groups to make it easier to understand their varied needs.
- [20:59 09/07/2004] <+Mike> Many species are small,
but some Bettas can reach up to 6' or so! They are found all
over, from lowland swamps to mountain streams, and many species
are found in only a small area - perhaps only a single stream.
Some species spend their entire lives hiding in the leaf litter,
while others spend their time in open waters. Some build large
bubble nests, while others build very small nests.
- [21:00 09/07/2004] <+Mike> Also, in general, the mouthbrooders
seem to prefer cooler water than the nest builders. I've had
them spawn in water that was in the upper 60's, and stop spawning
at all in water that was more 'Betta like' in the low 80's.
- [21:00 09/07/2004] <+Mike> Young mouthbrooders also
seem to generally be much larger and able to take baby brine
shrimp upon release, while most young bubble nesters need
at least a few days of infusoria before they are ready to
take baby brine. However, some domestic Betta splendens strains
will take baby brine as a first food.
- [21:00 09/07/2004] <+Mike> And that brings us to the
end of this 'talk' on Anabantoids. I hope you might want to
learn more. There are many excellent books out there on the
group, though most are long out of print. Some of the best
that you can easily find still in print are Bettas by Bob
Goldstein which covers many of the species in the genus in
detail, and Gouramis and Other Labyrinth Fishes by Gary Elson
and Oliver Lucanus. Both are published by Barrons and are
avai
- [21:00 09/07/2004] <+Mike> I know I covered a lot
in a short time. Are there any questions?
- [21:01 09/07/2004] <@craig> Thank you Mike!
- [21:01 09/07/2004] <@craig> Folks, if you have a question
for Mike, please type: /query craig I have a question
- [21:02 09/07/2004] <@craig> I'll start things off.
:-)
- [21:03 09/07/2004] <@craig> Mike, you mentioned the
pink gouramis will take crickets as food. Any specific type
of cricket?
- [21:03 09/07/2004] <+Mike> Personally, I use the canned
crickets from Jungle. They're made for feeding herps, but
are great for feeding large fish, too. My wife doesn't appreciate
the live cricket escapees. : )
- [21:04 09/07/2004] <@craig> That answered my second
question, how to feed them. Thanks.
- [21:04 09/07/2004] <+Christine> Thanks. Have you ever
heard of or experienced a trichogaster building and maintaining
a nest elsewhere besides the water surface?
- [21:04 09/07/2004] <+Mike> But the large live crickets
also work well.
- [21:05 09/07/2004] <+Mike> Only the leeri. They sometimes
build them under leaves down lower in the tank. The other
ones build such large nests that they will float to the surface.
- [21:05 09/07/2004] <+Mike> Of course, that doesn't
mean they won't. Each male has his own preferences.
- [21:06 09/07/2004] <+Christine> Okay, thanks. cuz
there's something "fishy" going on in one of my
caves
- [21:06 09/07/2004] <@craig> Anyone else have a question
for Mike?
- [21:06 09/07/2004] <+Mike> Could very well be. If
the surface is too choppy, or there are too many perceived
threats, maybe he is building one down low.
- [21:07 09/07/2004] <@craig> Sorry Christine, go ahead.
:-)
- [21:07 09/07/2004] <+Christine> So, would you recommend
pormoting breeding of these in a community tank?
- [21:08 09/07/2004] <+Christine> Or would the aggression
be too risky for other inhabitants?
- [21:08 09/07/2004] <+Mike> They'll breed, but the
other fish will eat the eggs/fry. It will be very stressful
on the male as he tries to guard the nest, too.
- [21:08 09/07/2004] <+Christine> Okay, thanks Mike
- [21:08 09/07/2004] <+Mike> It would be better to move
them (or the other fish) to another tank.
- [21:09 09/07/2004] <+Christine> alright, thanks:)
- [21:09 09/07/2004] <@craig> My interest in pink gouramis
is going to show here.
- [21:09 09/07/2004] <+Mike> How big are they?
- [21:09 09/07/2004] <@craig> Mike, can you give me
any hints on sexing pink gouramis?
- [21:09 09/07/2004] <@craig> One is 6 inches.
- [21:10 09/07/2004] <+Mike> Not until the female's
almost ready to lay eggs. Then she'll have a small white nub
coming from the vent. That is the egg tube.
- [21:11 09/07/2004] <+Mike> They've got a bit of growing
to do yet. Kissers usually spawn for the first time when they're
about 8" long and about a year and a half to two years
old.
- [21:11 09/07/2004] <@craig> So its going to be a matter
of having a group of them and hoping for a pairing?
- [21:11 09/07/2004] <+Mike> That's the easiest way.
- [21:11 09/07/2004] <+Mike> And boy, will you know
they've spawned!
- [21:12 09/07/2004] <+Mike> The surface will be covered
with eggs - and the other fish will be eating them!
- [21:12 09/07/2004] <@craig> Caviar.. :-)
- [21:12 09/07/2004] <@craig> Is there anyone else who
would like to ask Mike a question before I open the floor
for general discussion?
- [21:13 09/07/2004] <@craig> While I am waiting for
queries..
- [21:13 09/07/2004] <@craig> Mike, I would like to
extend my gratitude to you for taking the time to be here
with us tonight.
- [21:14 09/07/2004] <+Mike> Glad I could help out.
Hope I didn't put anyone to sleep! ; )
- [21:14 09/07/2004] *** craig sets mode: -m
- [21:14 09/07/2004] <@craig> The floor is now open.
:-)
- [21:14 09/07/2004] <@Jessica> Mike, that was an excellent
presentation.
- [21:14 09/07/2004] <+Mike> Thanks for inviting me
to speak!
- [21:14 09/07/2004] <@Jessica> Thank you so much for
coming :D
- [21:15 09/07/2004] <@craig> Cindy, thanks for hooking
him.. (pun intended)
- [21:15 09/07/2004] <+Mike> You're welcome! I always
love to talk about fish!
- [21:15 09/07/2004] <cindy> I just wanted to thank
Mike and tell him that when it comes to his opinion on allowing
the fish to adapt to local water and large frequent water
changes, he is preaching tothe choir here!
- [21:15 09/07/2004] <@craig> Yes he is. ;-)
- [21:15 09/07/2004] <+Mike> How're the Endler's doing
Cindy?
- [21:15 09/07/2004] <russ> Mike, that was probably
the best presentation of a group of fish that I have ever
heard. Even from past program presentations through various
societies I have been a memner of :-)
- [21:17 09/07/2004] <+Mike> Thanks Russ! It's much
easier talking while sitting down!
- [21:17 09/07/2004] <cindy> The most interesting I've
seen, too. One OT question, since I apparently don't know
how to /query Craig during the moderated part..can you tell
us a lettle aobut your fish room/basement/house situation?
It sounds like youare breeding quite a few species, or do
you breed them at different times?
- [21:18 09/07/2004] <+Mike> I've got 60 tanks, mostly
10's and 55's, with a few others thrown in for good measure.
- [21:18 09/07/2004] <+Mike> I work with "small
fish" under 4" in length. I try to breed everything
I can get my hands on.
- [21:18 09/07/2004] <+Mike> The more of a challenge
they are, the more I enjoy working with them!
- [21:19 09/07/2004] <@craig> And I thought 8 tanks
was bad. :-D
- [21:19 09/07/2004] <+Mike> Different fish will spawn
at different times, and my fishroom cycles through the year
as far as temperatures, etc.
- [21:20 09/07/2004] <cindy> I take it your significant
other isn't as obstinant as some of ours... I love the Endler's...they
are precious. I haven't lost one yet, and have shared some
with Gopi in WI and Shari in CA, so they are moving across
the U.S.
- [21:20 09/07/2004] <+Mike> My wife is a pseudo hobbyist
(she likes fancy goldfish!), though I'm sure I spend more
time on the hobby than she would like!
- [21:21 09/07/2004] <+Mike> We're both active in our
local club, too.
- [21:21 09/07/2004] <+Mike> I'm glad to hear they are
doing well and moving around the country!
- [21:21 09/07/2004] <@craig> I would love to have some
of them, but with the addition of the 210 I need to cut my
tank load down a bit.
- [21:22 09/07/2004] <+Mike> That silly little fish
has been among the most popular I've ever kept! Everyone loves
to see them when they come into the fishroom!
- [21:23 09/07/2004] <@craig> Hehe, I sorta did that
with loaches around here. ;-)
- [21:23 09/07/2004] <+Mike> BTW, Cindy, our club is
having a fishroom tour in September, and my fishroom is on
the list.
- [21:23 09/07/2004] <+Mike> Which loaches?
- [21:24 09/07/2004] <cindy> OMG- I'll be there...did
I miss the meeting this month? I keep meaning to join...The
first fry I got, the week after you delivered them in March,
are having fry of their own now. I find the largest four females
you gave me do eat fry, and are pretty good at it, so I think
I will move them to my small tetra tank.
- [21:24 09/07/2004] <@craig> I have too many species
of them to pick one Mike. :-D
- [21:25 09/07/2004] <+Mike> A friend in Indy set up
a 210 with many community fish, including a group of Zebra
Loaches. They keep spawning, and he can't catch a single one
of them! It's hilarious to watch him try!
- [21:25 09/07/2004] <+Mike> No Cindy. The meeting is
next Thursday at 7:30.
- [21:26 09/07/2004] <@craig> Friend, Indy? I'm in Lafayette!
- [21:26 09/07/2004] <+Mike> You know Charlie Grimes?
- [21:26 09/07/2004] <@craig> No..
- [21:26 09/07/2004] <@craig> Maybe I should tho. :-)
- [21:26 09/07/2004] <cindy> I'll be there. I want to
buy some plants for this 55, too. And I am going to get some
of them to Craig one way or another when his 210 gets established
and he settles into a new routine...he jsut wont believe how
little extra work a tiny ten of the Endler's are.
- [21:26 09/07/2004] <+Mike> I wouldn't admit it if
you did! : )
- [21:27 09/07/2004] <+Mike> They're almost carefree!
- [21:27 09/07/2004] <@craig> Cindy, give me some time.
The water situation here got me fairly rattled.
- [21:28 09/07/2004] <cindy> When I move the four largest
females, I'l have them coming out my ears...I figure you'll
be receptive about the time we decide to take the boys to
the Children's Museum in Indy...
- [21:29 09/07/2004] <@craig> Let me know when, my niece
hasn't been there yet, might make a day of it with you.
- [21:29 09/07/2004] <cindy> Sound like fun!
- [21:29 09/07/2004] <cindy> Mike, will you be bringing
plants to the meeting next week?
- [21:30 09/07/2004] <@craig> You have to come see the
clown loaches and most of all Pinkie!
- [21:30 09/07/2004] <cindy> I'd love to see them all...I
didn't get to see Shari's, and won't make that mistake again.
- [21:30 09/07/2004] <+Mike> I'll be bringing a few
for our HAP. Email me before the meeting and I'll send you
a list of what I've got right now.
- [21:31 09/07/2004] <@craig> Mike, Pinkie is my 6 inch
pink gourami who has literally been through hell and back.
- [21:31 09/07/2004] <+Mike> What happened to him?
- [21:31 09/07/2004] <@craig> Ignorance of the beginning
aquarist.
- [21:31 09/07/2004] <+Mike> Ouch. Good thing they're
tough!
- [21:32 09/07/2004] <@craig> He should be bigger than
he is considering his age, but he's still growing.
- [21:32 09/07/2004] <cindy> He's a beut now...you sure
can't tell he got a rough start...
- [21:32 09/07/2004] <+Mike> He'll catch up to where
he should be with good care now.

- [21:33 09/07/2004] <+Mike> But are you sure you're
ready for a foot long eating machine?
- [21:33 09/07/2004] <@craig> Oh yeah. :-D
- [21:33 09/07/2004] <cindy> He'll be the reigning king
of the 210...
- [21:33 09/07/2004] <@craig> I've got a 17" pleco,
so... ;-)

- [21:35 09/07/2004] <+Mike> Yes.
- [21:36 09/07/2004] <@craig> A juvie, no name yet.

poop like they doe in SE Asia!
- [21:37 09/07/2004] <@craig> They LOVE hikari algae
wafers...
- [21:37 09/07/2004] <cindy> Mike, I'll e-mail you Tuesday
to see what you'll have...
- [21:37 09/07/2004] <@craig> Oops..
- [21:38 09/07/2004] <cindy> Was it something we said?
- [21:38 09/07/2004] <JP> It's that little red button.
It's ebil.
- [21:39 09/07/2004] <cindy> Hey, while we are waiting,
can someone tell me what I shoudl do besides typing /query
craig I have a question during that part?
- [21:40 09/07/2004] <@Jessica> double click on craigs

- [21:40 09/07/2004] <@Jessica> yes
- [21:40 09/07/2004] <+Mike> AOL is starting to act
up
- [21:41 09/07/2004] <cindy> Boy, do I feel dumb...
- [21:41 09/07/2004] <@Jessica> don't cindy. its a different
thing :-D took me awhile to learn the controls
- [21:41 09/07/2004] <@craig> Cindy, we don't bite,
you could come around ya know. :-D
- [21:41 09/07/2004] <cindy> Mike I had a heck of a
time getting on tonight, so it may not be just AOL
- [21:41 09/07/2004] <+Mike> Okay. I keep appearing
and disappearing...I feel like a ghost!
- [21:42 09/07/2004] <cindy> It's jsut hard for me to
do more than read the transcripts...my boys were taking baths
and I had to get up 4-5 times while reading to separate them..don't
know how they can fight when one is in the tub and one isn't,
but they do...
- [21:42 09/07/2004] <@craig> You are doing just fine
Mike.
- [21:43 09/07/2004] <cindy> Will you be able to piece
it all together for the transcript?
- [21:43 09/07/2004] <@craig> Yes..
- [21:43 09/07/2004] <cindy> Cool!
- [21:43 09/07/2004] <@craig> Mike, if you can, could
you email me the text of your chat so I can fill in the missing
tidbits?
- [21:44 09/07/2004] <@craig> craighp@2cah.com
- [21:45 09/07/2004] <+Mike> Sure. I'll send it over
in a few minutes. Word okay?
- [21:45 09/07/2004] <@craig> Yep, all formats supported.
:-)
- [21:45 09/07/2004] <cindy> Maybe Mike will be gracious
enough to consider returning? I know you're busy, but this
really was the best Moderated chat yet, and I'd love to hear
you again...
- [21:46 09/07/2004] <@craig> I could also set him up
with some webspace..
- [21:46 09/07/2004] <cindy> Can I bring my camera to
the fish room tour, to share pics at Badman's?
- [21:46 09/07/2004] <@Jessica> Mike, I second the request
for a repeat. This was an excellent chat
- [21:47 09/07/2004] <+Mike> Thanks! I'd be happy to
visit and speak again!
- [21:48 09/07/2004] <russ> Thats great. Again great
presentation
- [21:48 09/07/2004] <@craig> Mike, do you have a website
somewhere around people can visit?
- [21:50 09/07/2004] <+Mike> Craig, the text is on it's
way.
- [21:50 09/07/2004] <@craig> k.
- [21:50 09/07/2004] <@craig> Now answer my question.
:-D
- [21:50 09/07/2004] <+Mike> Sure Cindy. Bring your
camera and snap away!
- [21:51 09/07/2004] <+Mike> As for a website: www.minifins.com
will be up soon. I have to fire AOL first - they won't let
me update it!
- [21:51 09/07/2004] <@craig> I have a few gigs to spare
here, yours for the asking.
- [21:52 09/07/2004] <+Mike> Thanks. A friend of mine
is hosting it on his server. I just can't send the files to
update it. AOL keeps kicking me off when I try.
- [21:53 09/07/2004] <cindy> Hey, is the photo on MASI
your fishroom? Oh! I just thought of one Q I couldn't get
in with my techincal difficulties...what is the difference
between green water and infusoria?
- [21:53 09/07/2004] <@craig> I would resist the urge
to say it but I can't.. AOL sux. :-)
- [21:53 09/07/2004] <@Jessica> lol
- [21:53 09/07/2004] <+Mike> I'll have a library of
articles that I've written over the years.
- [21:53 09/07/2004] <+Mike> That's Dorothy Reimer's
fishroom.
- [21:54 09/07/2004] <+Mike> Randy Carey has a couple
of photos of me and my fishroom on his site, but I'm not sure
of the URL's anymore. His site is Characin.com.
- [21:54 09/07/2004] <cindy> Very nice...I'll check
his out, too. Will that be on the tour, too? Or is it old
news to you guys? I've linked to a few of them on MASI here>>>
- [21:54 09/07/2004] <+Mike> Green water is single celled
algae in water. It's about as small a food item as you can
get.
- [21:55 09/07/2004] <cindy> So green water is phytoplankton
and infusoria are zooplankton?
- [21:55 09/07/2004] <+Mike> Infusoria is small one
celled and multicellular animals from the same size as the
algae to a size that isthat are big enough to eat the algae.
- [21:55 09/07/2004] <+Mike> Basically, yes.
- [21:56 09/07/2004] <+Mike> No. Dorothy is in London,
and Randy is in Minneapolis.
- [21:57 09/07/2004] <cindy> So the next time one of
the other teachers is asking for help with their nasty tanks
full of green water, I should nab a jar before dong massive
water changes and gravel vacs...and i really jumbled that
last part up...I'll be sorry to miss Dorothy's and will check
Randy's website for pics of your room...
- [21:58 09/07/2004] <+Mike> Yes! That's the best stuff
to start out many egg layer fry.
- [21:58 09/07/2004] <cindy> ..and I shared a couple
of your articles at MASI with members here...
- [21:59 09/07/2004] <cindy> You know... the funny thing
is..I've never figured out how to make a tank or jar like
that...how DO they do it?
- [21:59 09/07/2004] <+Mike> Great! The seahorse one
has been very popular. I've heard it reprinted at least a
dozen or so times.
- [21:59 09/07/2004] <cindy> That was the first one
I shared...
- [21:59 09/07/2004] <cindy> It got 2-3 people here
pretty excited...expecially Roxanne...
- [22:00 09/07/2004] <cindy> Do you have any SW tanks
currently?
- [22:00 09/07/2004] <+Mike> Green water is easy to
grow. Boil some rice grains and once they cool, pour them
and their water into a jar, then add some filter squeezins
and sit it on the window sill.
- [22:01 09/07/2004] <+Mike> I've only got one brackish
tank - with Syngnathus scovellii.
- [22:01 09/07/2004] <cindy> Plain old white rice? I've
tried the lettuce way and got nada...
- [22:01 09/07/2004] <+Mike> I'm working on getting
more seahorses...
- [22:01 09/07/2004] <+Mike> Yes. The lettuce way stinks
- literally.
- [22:01 09/07/2004] <cindy> Do you like the SW shop
in St. Charles?
- [22:02 09/07/2004] <+Mike> Haven't been in there in
a while. He used to run a good shop, though!
- [22:02 09/07/2004] <+Mike> I get stuff from Chuck
down at TWP on Watson. He's a MASI member, too.
- [22:03 09/07/2004] <cindy> I like to go in there and
dream...but will probably wait until I retire in a couple
years to jump...I am just afraid they won't be here that long...I
didn't know there were any other reef stores since that one
in Bridgeton closed....I'll go check out the one on Watson...
- [22:03 09/07/2004] <@craig> Sorry about that, had
a canister intake get clogged..
- [22:04 09/07/2004] <cindy> Are the new plants "shedding"
a few leaves?
- [22:04 09/07/2004] <@craig> Not that tank, my 75..
- [22:04 09/07/2004] <+Mike> Clayton Pet has great stuff,
both fresh and saltwater. But she's very proud of it...
- [22:05 09/07/2004] <@craig> Silly moss stuffs up everything..
- [22:05 09/07/2004] <cindy> Oops! Soes that mean you
don't want any more?
- [22:05 09/07/2004] <cindy> Even in dire straights?
- [22:05 09/07/2004] <@craig> More is good. :-D
- [22:06 09/07/2004] <@Jessica> moss rocks.
- [22:06 09/07/2004] <@craig> My 75 is a moss farm though,
I spend time everyday yanking away from the filter intakes.
- [22:06 09/07/2004] <@Jessica> wish i could convince
the stuff in my 55 to take off
- [22:06 09/07/2004] <+Mike> I better head out. My wife
wants to use the computer for a while. : ) Domestic tranquility!
- [22:06 09/07/2004] <@craig> Thanks again Mike!
- [22:06 09/07/2004] <@Jessica> Mike, many thanks :-D
- [22:06 09/07/2004] <cindy> You can never have too
much in my book, but I don't want or have it in all my tanks...Good
night, Mike, me too...
- [22:06 09/07/2004] <+Mike> Let me know if you want
me to talk again sometime.
