Africa: lower and middle Zambezi, Buzi, Pungwe (Ref. 52193), lower Sabi and Ludi Rivers (Ref. 42505), Luapula-Moero-Bangwelo (Zambian Congo system) (Ref. 42505, 52193). Also known from the Ruvuma and Rufiji rivers in Tanzania (Ref. 7248, 52193), lakes Malawi, Tanganyika (Ref. 4967, 52193) and Rukwa, and other eastward flowing rivers in Tanzania (Ref. 4967).
非洲: 三比河下游與中游, Sabi 下游與 Ludi 河, Luapula-Moero-Bangwelo 的系統; 包括馬拉威湖 (Nyassa) ，魯誇與坦噶尼喀。 在坦尚尼亞也已知來自尚比亞-剛果河流域 , 與 Ruvuma 與 Rufiji 河。 (參考文獻 7248)
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 34.0 range ? - ? cm
Max length : 75.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 52193); 最大体重: 10.0 kg (Ref. 52193)
背棘 (总数): 0; 背的软条 (总数): 65-75; 臀棘 0; 臀鳍软条: 17 - 19. Diagnosis: dorsal fin greater than twice the length of anal fin; dorsal origin nearer tip of snout than caudal fin base; snout 2-2.5 times in head length; caudal peduncle less than 4 times in standard length (Ref. 52193).
Found in caves and muddy areas, also hides among weeds (Ref. 13337). Favours quiet deep water with a soft muddy bottom (Ref. 52193). Forms shoals (Ref. 13337, 52193). Feeds on weeds (Ref. 5595) and insects but may also feed on small fishes (Ref. 5595, 52193) and fish eggs (Ref. 52193), blood worms (Ref. 13337), small crustaceans and mollusks (Ref. 13337, 52193). Active mainly at night; breeds during the rainy season, moving upstream in rivers after flood spates have receded (Ref. 52193). Migrations appears to occur at irregular interval as this fish is not a powerful swimmer and would not be able to cope with very high water current (Ref. 13337). Females carry 10,000-70,000 eggs; can give a mild shock when caught (Ref. 7248, 52193).
发现于洞穴与泥泞的区域了, 也躲在杂草中。 浅水型.(参考文献 13337) 吃昆虫，而且杂草也但是可能吃小鱼 (参考文献 5595) ，血液蠕虫，小型甲壳动物与软件动物.(参考文献 13337) 主要在晚上活动。 在雨季期间进行繁殖, 在河中向上游移动在洪水消退后。 回游似乎在不规则的间隔出现由于此鱼种不是一个有力的游泳者而且将不是能应付非常强的水流.(参考文献 13337) 母鱼抱卵 10,000-70,000个卵。 能给一个温和的惊吓当被捕捉时.(参考文献 7248)
