Freshwater; benthopelagic; pH range: 6.2 - 7.5; dH range: ? - 15. Tropical; 22°C - 26°C (Ref. 1672); 17°N - 4°N
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm SL male/unsexed; (Ref. 31256)
Africa: White Nile, Chad, Volta and Niger basins (Ref. 3202), including the Benue River(Ref. 7362).
Maximum TL was recorded at 22.2 cm (Ref. 7362). Occurs over a muddy bottom but may also be found over rocks. Feeds mainly on insect larvae but will also take algae (Ref. 6868). This is also an upside-down species (Ref. 4537). Oviparous (Ref. 205).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01380 (0.00618 - 0.03082), b=2.95 (2.77 - 3.13), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.7 ±0.28 se; Based on food items.
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (34 of 100) .
