Way of life
Buck-head mouthbrooders live over sandy areas in relatively shallow water at a depth of 3 to 15 meters. They are territory-forming , the males polygamous . A female lays 20 to 90 eggs, which are then taken into the mouth by the female ( mouthbrooders , mother family ). The fry hatch after 21 to 23 days.
Buck-head mouthbrooders often chase heavily burrowing species of cichlids and snatch up small crabs or other edible organisms that have been blown up.
