i dont have them yet, as im going to research them a little bit more and get my convict fry out of the tank before i do. im wondering how many could i put in this tank. my intentions are to breed the fish, but i also want a beautiful planted tank, so i dont think im going to be putting anything else in the tank, maybe some small catfish for clean up, bristlenose, or corydoras. would these be compatible? and how do i go about breeding them? if i have say two pairs would i run into aggression problems, or do i keep a higher female to male ratio? do they take good care of their fry? i was planning on leaving the fry in the tank, unless they or the other parents would eat the fry. thanks in advance.
