Occurs rocky or sandy-rocky substrates of rivers with rapidly flowing waters. Feeds on algae which grow on rocks in the river and cascades. Oviparous (Ref. 205).

Justification

Only known from two locations in the Rusizi and Luiche rivers. The population size is thought to be small as it is rare in fisheries catches. Area of occupancy is less than 500 km² and habitats are declining in quantity and quality due to increased water turbidity due to erosion on watershed.
