Biologie     Glossaire (ex. epibenthic)

Commonly occurs in running water, lakes and submerged vegetation in the Sudd, rare in fringing vegetation. Feeds on the bottom on mud, debris, insects, notably chironomid larvae and mollusks. Gravid fish are recorded throughout the year with a peak in the dry season (Ref. 28714).
