Common in a broad range of habitats from mainstream margins to floodplain channels and lagoons; preys on insects and small fish, including mormyrids and barbs, which are taken near the bottom; breeds in spring and early summer at low water before the annual floods arrive; relatively few eggs are laid and mouthbrooded; matures after 1-2 years (Ref. 7248). Agamous, maternal mouthbrooder (Ref. 52307). Also caught with drawnets.
