Africa: widespread over northern parts of southern Africa including the Cunene, Okavango, Upper Zambezi, Kafue, Zambian Congo and Limpopo systems; isolated populations occur in Malawi and on the eastern shores of Lake St. Lucia in Natal (Ref. 52193). May be confused with the bowstriped barb, Barbus viviparus (Ref. 7248) but differs in pigmentation details (Ref. 52193).
大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 7.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 52193)
背棘 (总数) : 3; 背的软条 (总数) : 8 - 9; 臀棘: 3; 臀鳍软条: 5 - 6. Diagnosis: With 2 distinct black lateral stripes along the body; lateral stripe begins clearly on the snout and runs through the eye and gill cover and down the body (Ref. 13337). The lateral line tubules are closely outlined in black, giving the line a tubular appearance (Ref. 13337). Anterior barbel about eye diameter and posterior barbel a little longer (Ref. 13337).
Occurs in floodplains, pools and shallow streams with vegetation. Feeds on detritus, algae, seeds, small invertebrates (Ref. 7248) and aquatic insect larvae (Ref. 13337). Migrates upriver to breed after heavy rains (Ref. 13337).
