生態學
; 淡水 大洋性; 河川洄游 (Ref. 51243). 熱帶; 11°S - 28°S
Africa: Kasai, upper Sankuru, upper Lualaba (Ref. 42019) and Luapula systems (Ref. 45616, 109499) (middle and upper Congo River basin) in Democratic Republic of the Congo and Zambia. Zambezi system including upper Zambezi, Kafue, Lake Kariba, lower Zambezi, Okavango, Cunene, Buzi (Ref. 7248, 94654) and Caprivi strip (Ref. 37065). Also from coastal north-east Natal to the Lake St. Lucia catchment (Ref. 13332).
非洲: Luapula ， Kasai, 在加丹加的 Lulua ，湖 Dilolo 與 Mweru 上游, 剛果; 對尚比西河下游， Kafue ，庫邦河， Okovango上游, 尚比西河流域的卡裡巴湖; 對 Pongola 南方的土吉拉北方, 納塔爾。

Maturity: Lm ? range ? - ? cm
Max length : 14.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 52193)
背棘 (總數) : 0; 背的軟條 (總數) : 10 - 11; 臀棘: 0; 臀鰭軟條: 18 - 19. Diagnosis: A slimmer fish than Brycinus imberi without a spot behind the head, but with a pronounced black lateral band (normally only visible on dead material) which ends in a caudal dash extending right through the caudal fin (Ref. 13337).
超過 B. imberi 的一個減肥者魚沒有斑點在頭部後面, 但是有在一個尾部的破折線徹底地延伸尾鰭中結束的一個明顯的黑色側面的條紋 (通常唯一的看得見的在死的材料上)。
Inhabits shallow, sandy or marshy areas (Ref. 13337). Shoals in clear, slow-flowing or quiet, well-vegetated waters. Often found together with the dashtail and the threespot barb and the close similarity of these species suggests mimicry between them. Feeds on small aquatic and terrestrial organisms. Preyed upon by tigerfish and observed to be eaten by a small crocodile during an upriver migration (Ref. 13337). Moves upstream during rains, possibly to breed. Ovarian egg counts from a large ripe female reach up to 12,000 eggs (Ref. 13337). Used as bait for tigerfish and largemouth bream (Ref. 7248).
棲息於淺灘, 沙的或沼澤區.(參考文獻 13337) 游入清澈的﹐緩慢流動的或安靜又植物生長良好的水域。 時常發現伴隨著 dashtail 與 threespot 鯉魚與這些種的接近類似意味著在他們之間的擬態。 吃小的水生與陸棲的生物。 被虎魚捕食了而且觀察在一個溯河迴游的時候被一隻小的鱷魚吃。 (參考文獻 13337) 在雨的時候向上游移動, 可能地繁殖。 卵巢的卵從一個大的成熟雌性的達到 12,000個卵計算。 (參考文獻 13337) 作為釣虎魚與 largemouth 鯉科食用魚的魚餌了。 (參考文獻 7248)
