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).

生物学特性     字汇 (例如 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).

通常发现于大河的上、下范围以及在 mixohaline 水域的河口区域中发现于了。 唯一的 Brycinus 种深入小的河川与溪流.(参考文献 2880) 被保持的水族馆: 形成 5个或更多个体的群体; 水族馆最小体型 100 公分.(参考文献 51150)
