Comments: Occurs in large river habitats (Ref. 12693).  Inhabits deep slow reaches during dry season (Ref. 37769).  Found in rapid-running mountain streams (Ref. 12975).  Not known to migrate, but may probably leave main stream for flooded forests during the periods of high-water.  Has not been found in any impoundments.  Omnivorous, feeding on detritus and algae along with worms, crustaceans and insects.  Marketed fresh (Ref. 12693).
