Found in shallow fringes in heavily vegetated areas but prefers deep, quiet water, slow-flowing channels and floodplain lagoons (Ref. 7248). Feeds on Nymphaea seeds, water insects, mollusks and fish material (scales of large cichlids) (Ref. 6465). Ovophilic, agamous (Ref. 52307) female mouthbrooder (Ref. 7248, 52307). Breeds in summer, probably spawning twice in the season; males mature at 15 cm, females at 12.5-15.0 cm; used as a snail control agent (Ref. 7248).

Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
