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).

肩部的斑點。 延伸至中央鰭條的尾柄斑紋尾部的。 體色銀色的有背部的區域呈綠色的與腹面部份白色。 雄性: 偶鰭紅色-紫羅蘭色, 腹鰭的末端絲狀突起也可能是紅色的-紫羅蘭色又鮮紅色斑點眼睛下面。 雌性: 鰭淡橘色, 每個尾葉用淡黃色的斑點，斑點眼睛下面橘色的。 頂骨囪門也當成魚時。 雄性: 絲狀的背鰭與臀鰭, 更快速地在成熟的雄性的體高成長。
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).
通常發現於大河的上、下範圍以及在 mixohaline 水域的河口區域中發現於了。 唯一的 Brycinus 種深入小的河川與溪流.(參考文獻 2880) 被保持的水族館: 形成 5個或更多個體的群體; 水族館最小體型 100 公分.(參考文獻 51150)
