Facultative air-breathing (Ref. 126274); Occurs in streams and lakes (Ref. 44091) and in weedy, mud-bottomed canals (Ref. 5723). Benthic (Ref. 58302). Nocturnal, feeds on algae (Ref. 13371), but will also feed on worms, insect larvae, and other bottom-dwelling aquatic animals (Ref. 44091). Spawning period peaks once a year (Ref. 56986). Reproductive behavior includes digging of burrows for egg laying (Ref. 82067). May exhibit male parental care (Ref. 56986).
Parental care may be exhibited by males (Ref. 56986).
