Don't mean to be a total nerd but incase anyone cares this highly taxanomically debated fish has recently be officially changed to "Hexanematichthys seemanni." Tragically, THOUSANDS of them are imported as tiny juvies every year, I doubt even 1% of them make it to maturity. I would have to say next to pacus this is the MOST MISPURCHASED fish by unsuspecting newbies.
The issues with this fish -
- Grows pretty large (over 1 ft) and more importantly is VERY ACTIVE and schooling and thus needs a big tank for a big active group.
- Adults do live in salt or brackish water. However, I will say IME all the large specimens I've seen were raised entirely in freshwater, despite the constant claims that they will stop eating and die is not switched to salt at 6"

with them they arn't called bala cats they have a few names Columbian shark, silver tip shark, and bull sharks (no relation to a REAL bull shark) and as they grow they need more salt in their tank, actully you can get them slowly adjusted to saltwater. Sorry for the bad spelling I'm half asleep. zzZzzZz...
