I have a mostly all male peacock/ hap 60 gallon with about 10 fish which are all 4"-6". I've had the tank a couple years and I'm upgrading to a standard 125 gallon. I'd like to add a few more male African Cichlids when I go over to the 125. One of the fish I'm considering is a 3" Venustus. Will it likely become too aggressive for the peacock tankmates or are 6" peacocks generally able to hold there own when the Venustus becomes larger than them?
