Inhabits large, slow flowing rivers (Ref. 43281). Commonly found in standing and slowly moving water of streams, canal, ditches and reservoirs. Moves into flooded forests and marshes during high water periods. Usually occurs around submerged aquatic or inundated terrestrial vegetation where it consumes some algae but mostly insects and zooplankton.
