Environment / Climate / Range
Freshwater; pelagic; depth range 50 - ? m (Ref. 34290). Tropical; 22°C - 26°C (Ref. 13614); 2°N - 7°S
Length at first maturity / Size / Weight / Age
Maturity: Lm 4.4  range ? - 4.7 cm
Max length : 9.0 cm SL male/unsexed; (Ref. 4967)
Lateral line low on the body and running along the lower part of the caudal peduncle. Cheek covered by thin suborbital bones. Silver with an overall nacreous sheen. Caudal fin yellow. Dead specimens with a distinct mid-lateral stripe (Ref. 34290).
Africa: Lakes Victoria and Kyoga, the Victoria Nile.
Found inshore and offshore (Ref. 34290). Juvenile fish migrate away from the shore after spending their larval stage in shallow areas (Ref. 33811). Adults stay near the bottom during the day and near the surface at night (Ref. 34291). Feeds on zooplankton (Ref. 13624) and surface insects (Ref. 34291). Rarely reaching a length greater than 8 cm SL (Ref. 34290). Also caught with dip nets (Ref. 4967).

Bayesian length-weight: a=0.00676 (0.00315 - 0.01450), b=3.07 (2.88 - 3.26), based on LWR estimates for species & Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.49 se; Based on food items.
Resilience (Ref. 69278
