Comments: Inhabits root mats of floating meadows in floodplains.  In the whitewater floodplain, juveniles are encountered in patches of floating macrophytes along lakes margins and along the edge of canos (drainage channels from lakes to the main river channels) and paranás (channels connected at both ends to the main river channel that transport whitewater through the floodplain).  Floating macrophytes form extensive floating meadows.  Undertakes aerial respiration by gulping atmospheric air into the hypervascularized posterior chamber of the gas bladder.  Feeds primarily on chironomid larvae, small insect nymphs and small crustaceans (Ref. 55508).
