Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 6.5 - 7.2; non-migratory. Tropical; 20°C - 26°C (Ref. 2059); 25°S - 29°S
Africa: small rivers, brooks and shallow parts of larger bodies of water, estuaries and lagoons in the warm coastal plains of Natal, South Africa, from the Pongola River southward to the Umlalazi River (Ref. 47311). Also in Transvaal, South Africa (Ref. 27139). Reports from the Okavango swamps in Botswana and the Cuanza and Cuilo in Angola probably refer to other species (Ref. 47311).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.5 cm TL male/unsexed; (Ref. 31267); 5.5 cm TL (female); common length : 3.0 cm TL male/unsexed; (Ref. 27139)
Occurs in inshore vegetated areas of lakes and well-vegetated streams. Feeds on aquatic insects, such as mosquito larvae and algae. Serial spawner, lays eggs on vegetation. Potential mosquito control agent (Ref. 7248). Not a seasonal killifish. Is difficult to maintain in aquarium (Ref. 27139).
