Africa: present along the Atlantic border of the African continent from Gambia to the Democratic Republic of the Congo (Ref. 2880, 5331, 80290, 81279). Generally found in upper as well as lower river courses and may even occur in brackish waters of estuarine areas (Ref. 2880, 81279). Only Brycinus species that inhabits smaller water courses (Ref. 80290).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Generally found in the upper and lower reaches of big rivers and also in estuarine zones of mixohaline waters (Ref. 2880). The only Brycinus species to penetrate small rivers and streams (Ref. 2880), but such specimens are always smaller than those in large rivers (Ref. 80290). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 100 cm (Ref. 51150).
