Length at first maturity / Size / Weight / Age
Maturity: Lm 17.4, range 13 - 15 cm
Max length : 39.0 cm TL male/unsexed; (Ref. 5309); max. published weight: 2.2 kg (Ref. 7248); max. reported age: 7 years (Ref. 7248)
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). A female mouthbrooder, 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).
Exhibits mouth brooding.
