hmmm, you mean columbian sharks? the catfish? Scientific name is Arius seemani, but I am not sure if this is the one you are talking about. That's the problem with common names lol
just one important thing. These cats will require brackish, and eventually close to full salt. Otherwise they develop skin lesions and infections, and probably will pass away.
Yeah, I read up on them quite a bit. I didn't know that when I purchased them but it gives me an excuse to have a BW tank. I have always wanted to have a tank with monos, scats, etc. Thanks Again
