生態學
; 淡水 底中水層性, usually 1 - 3 m (Ref. 35835). 熱帶
Africa: Lake Tana, Ethiopia (Ref. 35835, 128753). Also Didessa River in Ethiopia, but occurrences outside Lake Tana would suggest dispersion (Ref. 35835).
非洲: 在衣索比亞的塔那湖與其他的位置。

Maturity: Lm ? range ? - ? cm
Max length : 43.0 cm FL 雄魚/尚未辨別雌雄; (Ref. 35835)
背棘 (總數) : 0; 背的軟條 (總數) : 12 - 13; 臀棘: 0; 臀鰭軟條: 8. Head width less than 1.8 times in head length; head length more than 1.3 times in body depth; body depth less than 3.6 times in standard length; eye diameter more than 1.3 times in interorbital width; dark green; often with an extended, soft abdomen.
頭部寬度少於 1.8 倍頭長; 頭長超過 1.3 倍體高; 體高少於 3.6 倍標準的長度; 眼直徑超過 1.3 倍眼間骨寬度; 深綠色的; 時常有一個擴大的, 軟的腹部。
Occurs over muddy, sandy and rocky substrates all over the lake, preferably in water of no more than 3 m depth. Is a real macrophytivore: specimens smaller than 15 cm feed mainly on zooplankton and insect larvae; macrophytes increase in importance with size and finally make up most of the diet (Ref. 35835).
生活在泥濘的沙與岩石底部之上在湖中各處, 可能地在沒有超過 3 公尺深的水。 是一個真正的嗜食大型植物的動物: 比 15 公分小的標本主要捕食浮游動物與昆蟲幼生; 大型植物隨著體型增大而重要性增加而且最後組成大部分食性。 (參考文獻 35835)
