Inhabit almost any permanent fresh water, including flowing or still water of rivers, creeks, wetlands and lakes. Usually found around aquatic vegetation along the margins of streams or lakes. Water is fresh to slightly brackish and clear or tannin-stained (Ref. 44894). Occur at a temperature range of 11.0-26.0 °C (Ref. 1811). Benthic feeder, consuming a variety of microcrustaceans, insects and their larvae. Adults move into small side creeks and flooded streamsides to spawn between July and November. Peak spawning activity is in September and October. Reproductive biology and habits are typical of the family. Maturity is attained at the end of the first year, and maximum life expectancy is about 5 years (Ref. 44894).
Adults spawn between July and January.
