lol i just googled the Brachyplatystoma filamentosum and its the same fish that guy posted the thread on b4. the catfish that looks like a devil shark! simply amazing. but im torn between that and the wallago. i love how the wallago's tail evens out at the ends to look like a CKs tail. nature at its finest. on the other hand having a substitute shark has its perks too. ahhhhhh the choices...
