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).

Grootte / Gewicht / Leeftijd
Maturiteit: Lm ? range ? - ? cm
Max length : 14.0 cm SL mannelijk / geslacht onbekend; (Ref. 52193)
Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 10 - 11; Anale stekels: 0; Anale zachte stralen: 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).
Body shape (shape guide): fusiform / normal.
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).
