Moves into tributary streams and flooded forests along with many species of cyprinids and other species of visually oriented catfishes such as P. pleurotaenia when water transparency decreases. Feeds on mollusks and chironomid insects (Ref. 12975), small fish and prawns (Ref. 56749). Marketed fresh (Ref. 12693).
