I am assuming you meant managuense.Depending on the size of the fish and the tank,they will fight like hell.Juveniles should be ok together but,once they get 3-4 inches and depending on gender,they will fight.I live close to Bowie MD.I have a breeding pair of managuenses now with 2 week old fry in the tank.You have to see how aggressive these fish are once they have fry.This is my tenth pair of managuenses.They are my favorite cichlids.
