So we have a 70 gallon tank and new to African Cichlids. We just started with two peacock cichlids and one is already chasing the other around the tank. Mind you. They both came out of the same 20G tank at the fish store. Someone told me about the one or six rule. Either you Have only peacock or 6. is this true and how many females should we get. The plan is to get 12 cichlids total. Also, I get one person telling me that we can only keep African and not mix with other type while someone else said it is fine to mix. It has got us so confused. Any advice would help. Thanks.
