Leporinus is one of the few fish Ive never had nor have any experience with, I was wondering are they compatable with Red tail Black Sharks and Plain Black Sharks? And how about Cichlids? (Central + South American and African) How well do these guys defend themselves? Are they tough enough to coexist with cichlids as regular sharks can? Lots of questions! Thanx in advance to anyone with experience with these fish!!!!
