So I rescued a tank from a neighbor that moved out of the country. I have had tanks for the past 30 years but never Cichlids, at least not african. So to the best of my knowledge through my research I have a hap (peacock?) Mbunas, kribs, central american convicts (and a black skirt tetra? Don,t ask me what he is doimg in there, but no one bothers him). I have created many hiding spaces and lots of aggression is spread amongst the fish. The yellow mbuna is very aggressive and chases everyone around. I have had the tank setup for 2 months now and all of these fish came together when I got them. My question is I have another cycled 40 gallon bow front tank that is just sitting should I separate some of these fish? Which fish sbould go together? I've read conflicting things online. Suggestions from knowledgeable cichlid Keepers would be great, thank you.
