生態學
; 淡水 底中水層性; pH range: 6.5 - 7.0; dH range: ? - 10. 熱帶; 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.
非洲: 東的沿海河川與淡水湖泊從 Ruvuma(坦尚尼亞-莫三比克邊緣) 在納塔爾南部向南至 Vungu 。 通常侷限於 lowveld 與海岸的平坦區域了但是在較大的系統深入內陸例如凌波波河。 發現於 Kafue 河流域了。 (參考文獻 27607)
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 4 - ? cm
Max length : 7.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 52193)
背棘 (總數) : 0; 背的軟條 (總數) : 11 - 12; 臀棘: 0; 臀鰭軟條: 8 - 9.
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).
出現於長滿植物的溪中水潭與河與湖邊緣。 吃水生昆蟲與其他的小生物。 繁殖於夏天,成對的產卵魚產卵在水下的根部與植物上。 在一年之內達到成熟。 通常侷限於低地而海岸的平坦區域了但是在較大的系統深入內陸例如凌波波河.(參考文獻 7248)

Despite of the scientific name viviparus which translates into "live bearer", the species lays eggs like all the other members of its genus.非洲: 東的沿海河川與淡水湖泊從 Ruvuma(坦尚尼亞-莫三比克邊緣) 在納塔爾南部向南至 Vungu 。 通常侷限於 lowveld 與海岸的平坦區域了但是在較大的系統深入內陸例如凌波波河。 發現於 Kafue 河流域了。 (參考文獻 27607)
