Goldfish with large white spot
August 31, 2001 - 11:22 am
I have a fan tail I am keeping in a pond and it has a white
spot on one side of its head that goes from its mouth to
around its eye. I have had the fish for several months already
and the other fish do not seam to have this. I treated the
tank for two days with a teaspoon of non iodised salt for
each of the thirty five gallons. I did this once in the
morning and then at night. the fish is not getting any worse.
Before I tryed the salt treatment I used an ich medication,
but the spot is only in the one area so I don't think
its ich, but it also does not look too much like photos
of fungus I have found. Ps I have baby fish in a lower tank
that had pumped water back up from a water fall. I have
removed this hose but should I still treat both tanks since
I have four 8inch adults and about fifty SMALL babies in
a 125 gallon pond, since they had shared water?

Its hard to tell exactly what your fish might have. The
colors/patterns of some goldfish change as the fish grow,
so there is the slight possibility that your fish might
have just lost the color in that area, although the fish
usually lose the white over the other colors. It may be
some sort of bacterial infection. Take a look at pictures
of different types of bacterial infections and see if they
look anything like what your fish has. If you see any red
streaking in the fins, or anything that looks like an open
wound, that's probably a bacterial infection. Remember,
if you do have a bacterial infection, you need anti-biotics
to heal the fish. Ich medications only kill some parasites,
but do not work on bacterial infections, or anything except
ich for the most part. FYI: ich is very small white dots,
it almost looks like it has small crystals of salt or sugar
stuck to the fish. As far as salt goes, you never need to
add salt more than once, unless you've done a water
change. Salt stays in the water once its added, it doesn't
break down or evaporate. The only way to remove salt is
by removing water from the tank. With each water change,
you dilute the concentration of salt in the water. When
adding salt after a water change, only enough salt for the
amount of water you replaced. For example, if you take out
15 gallons of water and replace it, only add enough salt
for 15 gallons.
As far as treating both tanks, I would wait until I figure
out what is wrong with the fish, and wait to see if any
of the other fish appear to be sick.
Hope this was of some help. I'm sure some other people
will post other possibilities I hadn't thought of.

Thankyou for the info. I am really sure it is not a color
change since the area was minimally cotton like before I
added the salt. It might be mouth fungus, but I thought
it was odd that the fish only had it on the one side and
that it extended from the mouth and up around the one eye.
I did not notice any red or any other marks on the rest
of its body.

I just found a photo of a fish with a spot like mine the
book said it was fungus, I think I was stumped since it
was only on the face. What do I do to treat it and sould
I treat the other tank.

Goldfish do, indeed, like a "little" salt in the
water, but if you have added 70 teaspoons of salt to 35
gallons of water twice, you have added way too much. The
rule of thumb ordinarily with salt is l tablespoon per 5
gallons of water and do this only one time unless you have
done a water change per G's advise. You are creating
a very high salinity value that can actually burn freshwater
I would do a water change even tho this is a pond to remove
some of the salt. Then I would treat with anti-fungal medication
made especially for ponds along with a mild dose of antibitoic
to head off any bacteria that may occur from the fungal
infection. An idea arrangemnt would be to remove this particular
fish to its own quarters for treatment, but this may not
be possible. A true fungal infection will look like a growth
of cotton. If this is just a white marking or coloration
of the scales, I would have to agree with G that it is just
the fish changing colors as he is aging. I once had a plain
comet "gold" fish. He lived for a very long time,
but in his 3rd year, he gradually started changing colors
and eventually my goldfish was completely "white"
Just be absolutely sure if you can that you are using the
right treatment for the right disease if, indeed, there

If you still have trouble identifying what exactly it is,
and the fish doesn't seem to be getting better, try
taking it in to your local LFS.
We have people bring in sick fish for us to look at on a
regular basis where I work. Its nice for both the customer,
and the employee, as it takes the guess work out of what
is wrong with the fish.
Some people have even brought in digital cameras, polaroids,
and one gentleman brought in a video of his sick fish.
If you have a dependable fish store near by, it might not
be a bad idea.
Remember, true fungus is very cottony, there is a type of
bacterial infection that resembles a fungus, but is less
cottony than a true fungus infection (it is commonly
referred to as a fungus, unfortunately). If the fungus
is only in one place, its possible that the fish simply
scraped that part of its head on a rock, pot, or some other
decoration/piece of equipment in the pond. This could especially
be true if all of your other fish appear to be fine, and
you have no problems with water quality.
Good advice for ANYONE who owns fish is to keep in mind
that fish generally get sick for a reason. In order to help
cure the problem, and keep it from happening again, the
problem needs to be identified and taken care of. Just as
a hint, a lot of diseases are caused by stress, which I
find can be linked to deteriorating (poor) water
quality, among other things.
I'll stop now before I start going into great detail.
Hope this helps.

Now I feel bad about adding the salt, but I was following
dirrections in a goldfish book That had lots of disesaes
and treatments listed. I was considering seperating the
fish, but I did not have a hospital tank set up, and there
is only one other fish in with the sick one, so I thought
if it might be contagious that i should treat both. They
are always near each other. I also cosidered the pet store,
but in the past when my other fish bred I asked their "specialist"
and it was a guy who did not know much. The spot deffinatly
looked a little cotton like but not as much as all of the
phots I have been finding. I I am sure he is not changing
colors since I have seen this before when one of my older
ones lost her gold spots and went totally white. The other
thing G mentioned was that the fish could have scraped its
self. I did give the fish in both ponds a cement cinder
block so they could hide from cats, and so the white ones
would not sun burn. The water is clear as can be and I keep
all of the debris out of the pond. The spot does look slightly
cotton like, but like G mentioned not as cotton like maybe
as a true fungus. I have had most of the fish for the last
6 or seven years and have never seen this. I have had all
of the fish but two since April (excluding the new babies).
So I don't beleive it was brought in by one of the fish.
The bacterial infection that resembles a fungus sounds a
lot like what this looks like It is slightly cotton like.
Sould I treat the fish for just bacteria, or fungus or both.
I would hate to lose this one. Thanks for all the help.
I will do a water change asap to get the salt down. This
is the first problem in 6 years, I would hate to lose a
fish after this many years. Please give me any Ideas, and
I would be glad to answere questions.

"I also cosidered the pet store, but in the past when

Thank you Jennifer!!! This is a point I have been trying
to stress to G. Most of the folks moderating aquarium messageboards
have far more experience and knowledge than LPS personnel
at any given store or any books that you might find available.
Now on to your post.........
It is very hard to try to describe an illness over the boards.
It is even harder to try to tell someone exactly what may
be going on and how to treat. First on the agenda, do take
care of the overabundance of salt. Secondly, if you think
this may be columnaris or flexbacter, I would treat with
antibiotic therapy. You will have to be the dectective here
to decide which antibiotic and dosage is correct for a pond
setting. I am sure factors of gallonage, temperature or
other circumstances in a pond setting vary from an indoors
aquarium. Since I am not well versed on ponds, I won't
be of much help to you.
I think I proably would also treat with an antifungal medication,
but here again, without being able to exactly determine
the illness, what antibiotics are preferred and what antifungal
medications are available for ponds, I can't really
give you step by step instructions for treating.
You might be wise to search for a website or messageboard
that deals stricty with ponds and outdoor situations. Someone
more experienced with these will certainly have the valuable
information to help you.
Keep us posted, if you will, on the outcome. Then you will
be able to "teach" us something new.

Thank you soooo much for all of your ideas it has allowed
me to look up photos and at least eliminate some of the
possibilities. I will let you know what happens. I also
posted a question on my gold fhis fry. Does anyone have
experience with gold fish fry color?
September 03, 2001 - 12:34 am
I hope your fishie gets along okay. I used to keep goldfish,
but had little experience with fry. I will say here that
when I kept goldfish, their colors would change so my feeling
it that they are okay and just changing colors as they get
older. Be sure to let us know how the big guy gets along.
September 03, 2001 - 02:22 pm
Thanks a lot Kick! The sick one was treated with PENICILLIN
made by Aquatronics. It says it works on Bacterial and fungal
infections. She appears to be doing better. The product
was for pond use so I think we got our best option.
The fry are different sizes and are changing colors all
at different times. So far I have all calicos from one gold
and one calico parent. Some of the fry are about two inches
long and were all black, but are now turning gold in spots.
Its really neat to watch. Thanks again!
September 03, 2001 - 05:23 pm
Jennifer, you are very welcome and so glad that we could
help. I bet it really is neat watching those little guys
grow and change. I was never lucky enough to have fry when
I kept goldfish. I only kept two as they were pretty good
size, so I imagine they were both the same sex. Keep us
posted on how everything turns out for you.
