Occurs in lotic and lentic freshwater bodies (Ref. 7300). Inhabits vegetated margins of streams, billabongs, drains, dams and swamps in still or gently flowing water. Forms small groups and is a very common prey item for introduced fishes, such as the Redfin perch and trout. Feeds on small crustaceans, insects and their larvae. Breeds from September to January, when water temperatures rise above 16°C. Reproductive habits and biology are typical of the family. Maximum life expectancy is about 5 years (Ref. 44894).
