So.. I have a cichlid tank with about 15 mid sized fish. I just recently found a lake where I can catch the Mayan cichlids.. or peacock bass I guess some call them? I caught one and have it in a separate tank alone and he seems to be pretty aggressive compared to the others.. is that because hes from a lake, and not from a breeder? Will he calm down and act more domesticated if I keep em solo for a few days? Lol or should I throw em back?
