The species Barbus degeni Boulenger, 1902 is considered a synonym of Labeobarbus intermedius (Rüppell, 1835) in Eschmeyer (CofF ver. May 2011: Ref. 86870). It is treated here a synonym of Labeobarbus nedgia Rüppell, 1835 according to Nagelkerke & Sibbing (1997: Ref. 35835).
Environment: milieu / climate zone / depth range / distribution range
生態學
; 淡水 底中水層性; 深度上下限 1 - 6 m (Ref. 35835). 熱帶
Africa: Lake Tana and its tributaries, Ethiopia (Ref. 35835, 96382, 128753); also known from another lake and several rivers in the Ethiopian region (Ref. 35835, 96382).
非洲: 在衣索比亞的塔那湖與其他的位置。
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 70.7 cm FL 雄魚/尚未辨別雌雄; (Ref. 35835)
背棘 (總數) : 0; 背的軟條 (總數) : 11 - 13; 臀棘: 0; 臀鰭軟條: 8. Lower lip forming a distinct median lobe; upper lip well developed, often with a median fleshy lobe; if lobes are absent, often a fleshy 'nose' is present; operculum depth about as large as ventral cheek length; head length less than 1.2 times in body depth.
形成一個的下唇明顯的中央葉; 上嘴唇發展良好的,時常具有一個中央的肉質葉; 如果葉缺席, 時常一肉質的 '鼻子' 存在; 鰓蓋深度大約與腹的頰長度一樣大; 頭長少於 1.2個倍體高。
Occurs especially over rocky substrates in water of no more than 6 m depth. Is a macro-benthivore: specimens smaller than 15 cm FL mainly eat insect larvae, but switch to a more diverse diet when their size increases: adult insects, mollusks and detritus become more important; large specimens are the only barbs in Lake Tana that eat freshwater crabs of the genus Potamonautes; and also eat some fish (Ref. 35835).
生存在沒有超過 6 公尺深的水尤其在岩石的底部之上。 是一個大型底部覓食者: 比 15 公分 FL 小的標本主要地吃昆蟲幼生, 但是當他們的大小增加的時候轉變成一個比較不同的食性: 昆蟲成蟲, 軟體動物與碎屑變得更重要的; 大的標本在吃本屬 Potamonautes 的淡水螃蟹的塔那湖是唯一的鯉魚; 以及吃一些魚.(參考文獻 35835)
