Environment: milieu / climate zone / depth range / distribution range

; agua dulce bentopelágico. Tropical; 13°N - 11°N
Africa: endemic to Lake Tana and its tributaries, Ethiopia (Ref. 35835, 96382, 128753).
Tamaño / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 82.4 cm FL macho / no sexado; (Ref. 35835)
Espinas dorsales (total): 0; Radios blandos dorsales (total): 12-13; Espinas anales 0; Radios blandos anales: 8. Lower jaw extending anteriorly of the upper jaw by at least the thickness of the upper lip; upper jaw length more than 1.3 times in lower jaw.
Has a small preference for rocky substrates and waters less than 6 m deep. Is a partial piscivore: specimens smaller than 15 FL mainly eat insect larvae and zooplankton, but also some fish. With size, the amount of fish in the diet increases, as does the amount of plant material, while the amount of insects decreases and zooplankton disappears altogether (Ref. 35835).
