Etymology: Enteromius: Greek, enteron = intestine + Greek, myo, mys = muscle (Ref. 45335). More on author: Weber.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; 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 Natal. Generally confined to lowveld and coastal plain regions but penetrates inland in larger systems such as the Limpopo. Found 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.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 4 - ? cm
Max length : 7.0 cm SL male/unsexed; (Ref. 7248)
Occurs in vegetated pools of streams and rivers and lake margins. Feeds on aquatic insects and other small organisms. Breeds in summer, breeding pairs lay eggs on submerged roots and vegetation. Reaches maturity within a year. Generally confined to low-land and coastal plain regions but penetrates inland in larger systems such as the Limpopo (Ref. 7248).

Despite of the scientific name viviparus which translates into "live bearer", the species lays eggs like all the other members of its genus.
