Comments: Found in clear water creeks surrounded by dense gallery forest, with bottom composed of rocks, pebbles and sand, with submerged litter only at the bottoms of the larger and deeper pools.  Also occurs in larger water bodies with scarce marginal vegetation and the substrate composed solely of sand.  Feeds on diatoms, cyanobacteria, green algae and organic matter (Ref. 47265).
