Africa: Cunene River system (Angola and Namibia), Okavango River, upper Zambezi, and Kafue Rivers (Angola, Namibia, Botswana, Zambia, Zimbabwe)(Ref. 5693), and Luapula-Moeru (Congo River system)(Ref. 361, 11970, 41590, 42135, 45616) in Democratic Republic of the Congo and Zambia.
Length at first maturity / Size / Weight / Age
Maturity: Lm 20.0, range 18 - 22.5 cm
Max length : 41.0 cm SL male/unsexed; (Ref. 7248); max. published weight: 2.5 kg (Ref. 5693); max. reported age: 9 years (Ref. 7248)
Also caught with drawnets. Occurs in well-vegetated swamps and along the edges of rivers. Also occurs in fast-flowing reaches over sand and rocks. Feeds on small fish, shrimps and insects. A mouthbrooding species which breeds in spring (Ref. 6465).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Female incubates eggs in her mouth. Parental care is exercised for a short while after hatching when the juveniles move off to shallow grassy areas and there they remain, in the Upper Zambezi, until floodwaters recede and force them back to the main river. They seek refuge in lagoons and backwaters until reaching a size large enough to avoid predation by tigerfish in the open waters of the river.
