Comments: Usually found in clear, relatively fast waters with gravel and boulder (Ref. 27732).  Occurs in medium to large-sized rivers (Ref. 12975).  Moves out onto the floodplain during high water where it feeds on algae, periphyton, phytoplankton and some zooplankton.  Used to make prahoc in Tonlé Sap, Cambodia.  Occasionally imported in the aquarium trade. (Ref. 12693).
