Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic, usually 3 - ? m (Ref. 35835). Tropical; 13°N - 11°N
Africa: endemic to Lake Tana, Ethiopia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 42.5 cm FL male/unsexed; (Ref. 35835)
soft rays: 8. Eye diameter less than 1.5 times in snout length, less than 1.1 times in interorbital width, and less than 5 times in head length; head length the same as body depth; lower and upper jaw close equally or lower jaw extends anteriorly from upper jaw; usually a well developed nuchal hump.
Occurs over muddy, sandy and rocky substrates (with slight preference for rocks), usually in water deeper than 3 m. Feeds on insects (both larvae and adults); small specimens also eat zooplankton, while large ones sometimes exclusively feed on fish (Ref. 35835).
