Just to let you know, not only can these guys
get large, they can live a loooong time! Mine is going on thirteen now!
He has outlived tankmates several times over. He used to shoal with
his best friends, two Bali sharks who managed to live to 7 and 9 respectively.
I did not do anything special for him except allow his water to stay
acidic quite by accident. He likes it best between 6.3 and 6.5. A sturdy
top and no unsupervised opening is a must because they will jump out
thru holes that seem impossible. Fortunately, once they get some size
on them, they make a loud enough thud that you will know and can run
catch them and put them back in. They also gulp air directly, so if
it takes a little while they have a better chance. They like to do this
occasionally while in the tank as well. Don't put any plants live or
plastic in with them that you don't care whether they get destroyed
either! I wholeheartedly agree with the assessment about being aggressive
with each other. We got him a 'friend' about ten years ago and then
had to get another tank for said friend when they began fighting nonstop.
She lived for nine years herself! If you are not in it for the long
haul, try another fish!
The fish is semi-proachalodus tienerus slightly
different then flagtail which is semi- proachalodus insignias but as
was stated to be kept together you need a large group they get better
with size and they do get rather large over 10" I have 8 14"-8" pieces
very colorful very beautiful fish,they are mainly vegetarian in the
wild but will accept a large variety of feeds in captivity give them
some spirlina flakes or tabs or pellets in their diet plus some tetra
color bits and you will have fish with the most intense red fins you've
ever seen. They also get a very large dorsal fin not as large as insignias
but big good luck with this awsome fish
That's a flagtail prochilodus. I had one awhile ago. Prefers
greens over meats but is an oppurtunistic feeder. They like the company of
others and need atleast a 55g.
They seem to like the company of other fish, but not
necessarily each other. From my experiences, they start to get aggressive with
each other as they get larger (although they're generally fine with other
fish). Unless you have a large group, you're probably almost better
sticking with one. (For a large group I would probably say at least 6
or 7, everyone I know that's tried 4 or 5 has ended up with one...even in a (150).
