Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical; 13°N - 11°N
Africa: endemic to Lake Tana, Ethiopia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 50.5 cm FL male/unsexed; (Ref. 35835)
soft rays: 8. Anterior barbels very thick and dark, length less than 5.5 times in head length, less than 2 times in gape height, longer than eye diameter; oral gape inferior; dorsal head profile irregular, convex caudally and with a 'bump' caused by premaxillaries.
Over muddy, sandy and rocky substrates all over the lake, preferably in water deeper than 6 m. Feeds mainly on insect larvae, small mollusks, and detritus.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00195 - 0.00935), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.35 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High vulnerability (58 of 100) .
