Occur often far up rivers, but also in estuaries and in Lakes Alexandrina and Albert near mouth of a river (Ref. 188). Most commonly inhabit streams coursing through relatively dry eucalyptus-scrub or desert areas, preferring sluggish or quiet waters (Ref. 5259, 44894). Also found in saline lakes (slightly less salty than sea water). Tolerant of water temperatures between 9° and 38°C and pH 4.8-8.6. Although these fish have a wide tolerance of temperature and pH, they are susceptible to oxygen depletion and are usually the first to perish when ephemeral habitats begin to dry up. Common length is 15-20 cm (Ref. 44894). Frequently noted in large shoals that feed on benthic algae; also feed on insects and small crustaceans. Spawning may occur repeatedly in the north with a peak during the wet season; probably annual in the south (Ref. 5259, 44894).

In more northerly part of its range, spawning may take place several times over the year but is probably annual in southern localities.
