The Aquarium

These large fish require an aquarium of at least 150 centimeters. Use coarse-leafed plants and place them in a flowerpot in the ground so that they cannot be dug out. Shelters can be made from bogwood and stones. Rounded gravel must be used as substrate so that the fish cannot injure their mouths. A powerful filter is needed to keep the water clear since they are rather large eaters and like to play with the substrate looking for food.

Water parameters

Temperature: 20-24 degrees Celsius.
PH: 7-8
GH: 16-20

As said, they are big eaters, give them live and frozen food like beef heart, mussels, shrimp, mysis, krill, mosquito larvae, coalfish fillet, small fish, and artemia, also dry food and cichlid sticks.


These cichlids are best kept as a couple, adult fish can be quite aggressive towards other residents in the aquarium, so keep them together with other strong cichlid species. They are territory formers, so give them sufficient space and shelter.
