In Lake Victoria confined to shallow coastal areas (Ref. 34290, 104654), in water less than 20 m deep (Ref. 12526, 34290). Omnivore, feeding on aquatic plants, surface insects and small fishes, and sometimes on molluscs (Ref. 4903, 12526, 104654). Known to run up rivers and streams in Lake Victoria during rainy season (Ref. 4903). Apparently rare since introduction of Lates (Ref. 4967).
