For anyone that is interested in these fish:
1. They grow to probably 12" - 16" so you will need a big tank (at least 6 foot).
2. They are pretty aggressive, they will probably try to kill any other fish in the tank.
3. Central American fish pH of at least 7.5, keep temps in the 76 - 83 degree range.
4. Prefer hard water
(All pf that sound right Mo?)
That said, they are a really cool fish with personality and attitude to spare!
