Facultative air-breathing (Ref. 126274); Inhabits quiet streams, sloughs, swamps and other wetlands over sand, mud and debris, often among dense vegetation. Juveniles also found among aquatic vegetation, often forming schools of 10-12 individuals (Ref. 39069). An introduced species in Europe which usually occurs in small isolated ponds and peat bogs (Ref. 59043). Oviparous, larvae remain in algal nest for about 6 days (Ref. 39067). Spawning takes place in April and May (Ref. 30578). Feeds on insect larvae, worms, mollusks, crustaceans alevins. Experimental studies show that this species can tolerate acidic environment, particularly, at ph values ranging from 4.0 to 7.0 where no mortality or significant changes in blood plasma osmolarity and haematocrit was observed (Ref. 59260).
