Comments: Occurs in large rivers in the dry season and moves to medium-sized rivers in the wet season.  Found at midwater to bottom depths in clear water.  May move into flooded forest habitats immediately adjacent to rivers, but does not occur over fine-grained sediments, preferring rocks instead.  Not known to thrive in impoundments.  Feeds on zooplankton, worms and algae.  Marketed fresh (Ref. 12693).
