Ecology of Australoheros facetus
 
Main Ref. Andrade, P.M. and F.M.S. Braga, 2005
Remarks Common in creeks, rivers, swamps and lakes. An opportunistic diurnal feeder, eating detritus and plant material, preying on small aquatic animals, including small fish. Very resistant to low temperatures. (Ref.59043). No seasonal or size-related changes in feeding intensity were found, but the diet changed across rivers, over time and throughout ontogeny (Ref. 75855). Fish tend to use the most abundant and easily accessible food items (Ref. 75855).
