In Lake Victoria it occurs over hard and soft substrates, but is more common over soft bottoms and in water over 13 m deep; feeds on gastropod molluscs and insects (mainly chironomid larvae), and to a minor extent on fishes and ostracoda; able to extract the flesh of snails without crushing their shells (Ref. 12526).
