Length at first maturity / Size / Weight / Age
Maturity: Lm 17.5, range 15 - 20 cm
Max length : 35.0 cm SL male/unsexed; (Ref. 7248); max. published weight: 1.5 kg (Ref. 5693); max. reported age: 6 years (Ref. 7248)
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.
