In the aquarium these cichlids are best kept in cichlid community tanks that are preferably large. Peacocks can be housed with other medium sized non aggressive cichlid fish from Lake Malawi
. In the wild these fish defend large open areas where they spawn in pits so the aquarium should offer a lot of caves for hiding but areas where territories can be established. Some hobbyist keep multiple females with one male in the tank because have multiple males may cause fighting so its best keep one male if possible.
