Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic, usually 6 - ? m (Ref. 35835). Tropical; 13°N - 11°N
Africa: endemic to Lake Tana, Ethiopia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 39.4 cm FL male/unsexed; (Ref. 35835)
soft rays: 8. Head length less than 4.2 times in standard length; head longer than pectoral-ventral length; anal fin length less than 0.75 times in head length; lower lobe of caudal fin less than 1.25 times in head length; eye diameter at least 5 times in head length; maximally 32 scales on lateral line; silvery.
Occurs over muddy, sandy and rocky substrates, preferably in water deeper than 6 m. A real benthivore: specimens smaller than 10 cm FL mainly eat insect larvae, but also zooplankton and ostracods. With increased size, adult insects, mollusks and detritus also become important (Ref. 35835).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00568 - 0.02543), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.43 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
): Moderate to high vulnerability (49 of 100) .
