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).

الأشواك الظهرية (المجموع) : 0; الأشعة الظهرية الناعمة (المجموع) : 9 - 10; شوكة شرجية: 0; أشعه شرجية لينه: 15 - 20; فقرات: 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).
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).
