Lives in streams, backwaters, lakes, swamps and estuaries. Occurs in brackish estuaries and inland salt lakes. Most common in slow-flowing streams and still waters, shoaling near the surface or around the cover of aquatic plants and woody debris. Forms large aggregations in open water (Ref. 44894). Feeds on aquatic insects, microcrustaceans and algae. Spawns throughout the Murray-Darling river system. Breeds between July and March (mostly in spring) (Ref. 44894). Spawning temperature is about 15 °C. Newly hatched larvae measure 4.8 mm TL on the average. Eggs are laid among aquatic vegetation and hatch in about 10 days. Sexual maturity is attained by the end of the first year (Ref. 44894). Eaten fresh or canned.
生活在溪流，洄水區，湖，沼澤與河口。 吃水生昆蟲，小型甲殼類動物與藻類。 在 Murray-Darling 河流域各處產卵。 產卵溫度是大約 15個 ° C. 一般說來最近孵化了仔魚尺寸 4.8 mm TL 。 被吃生鮮地或罐裝的。
