Africa: Limpopo River, Incomati River, Pongolo River, Saint Lucia system and Mkhuze River in Botswana, Zimbabwe, South Africa, Swaziland and Mozambique (Ref. 116496). Also known from Okavango (Ref. 7248, 52193), upper Zambezi system (Ref. 7248, 52193) and middle Luapula (upper Congo River basin) in Zambia (Ref. 52959). Reports from Orang River below Augrabies Falls (Ref. 7248, 33857, 52193) refer to Engraulicypris gariepinus (Ref. 116496).
非洲: 在納塔爾北部的庫內內河，奧塔萬戈河，尚比西河上游系統與沿海的河川從凌波波河東部到 Umfolozi。 一個孤立的族群在奧格拉比斯瀑布之下被發現於橘河。

背棘 (总数) : 0; 背的软条 (总数) : 9 - 10; 臀棘: 0; 臀鳍软条: 15 - 20; 脊椎骨: 37 - 38. Diagnosis: Caudal fin membrane clear towards vivid yellow at fork; anal fin extending two thirds of length of caudal peduncle; caudal peduncle moderately long; operculum entirely, not partially, shiny; body midline silver, not black; iris dark to light grey, not white; head with tubercles along lower jaw and lower head in breeding males; snout rounded, not pointed, darker dorsally; pelvic fin melanophores absent (Ref. 116496).
Body shape (shape guide): fusiform / normal.
Pelagic species preferring close proximity to substrate and seeking out slacker areas such as backwater, eddies and pools below riffles (Ref. 116496). It occurs in shoals and prefers well-aerated, open water in flowing rivers, favouring the upper stratum (Ref. 7248, 52193, 116496). Feeds from water column on planktonic crustaceans and insects, such as midges and ants (Ref. 7248, 52193, 116496). Breeding occurs in early summer; appears to migrate up streams in spring to breed where it is found in tributaries (Ref. 7248, 116496).
出现于浅滩; 偏爱空气流通的, 流动河的开放水域。 从水中捕食浮游性甲壳动物与昆虫例如蚊与蚂蚁。 被夜晚的灯光吸引了。 繁殖于初夏。 (参考文献 7248)
