nice how big are your now? mine is about 4 inches, so he has some time before he'll start getting dangerous for my albino female krib.
he's so cool to watch hunt, no strategy just swim up to the fish and eat it, i don't know how it works. haha he's better at eating fish then my ctenopoma!
I kept one of these i think many years ago,its definitely Ameiurus sp, that theres no doubt,the adipose,anal and square caudal fin points to that,if my memory serves me right it was called a marble bullhead,scientific name (Ameirus marmorata).
