; zoet water benthopelagisch; pH range: 6.5 - 7.0; dH range: ? - 10. Tropical; 22°C - 24°C (Ref. 1672); 13°S - 30°S
Africa: East coastal rivers and freshwater lakes from the Ruvuma (Tanzania-Mozambique border) southwards to the Vungu in southern KwaZulu-Natal; generally confined to lowveld and coastal plain regions but penetrates inland in larger systems such as the Limpopo (Ref. 7248, 52193). Also in Kafue River system (Ref. 27607). Also reported from the upper Zambezi and the Kwango River (middle Congo River basin) in Angola (Ref. 11970), but the latter is unconfirmed in other sources and needs confirmation. Reported as Enteromius cf. viviparous from the Zambezi, Okavango and Kunene in Angola in Ref. 120641.

Found in vegetated pools of streams and rivers and lake margins (Ref. 52193). It feeds on aquatic insects and other small organisms (Ref. 52193). Breeds in summer, breeding pairs lay eggs on submerged roots and vegetation (Ref. 52193). Reaches maturity within a year (Ref. 7248, 52193).
