Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Oceania and Asia: Rivers of Australia and southwestern Papua New Guinea (from Fortescue River near Dampier Archipelago in Western Australia, eastward in rivers through the Northern Territory and Queensland south to the Murray-Darling system; also the Finke River, affluent to Lake Eyre; Bensbach River (Ref. 6993) and Digoel River in New Guinea.

Biology     Glossary (e.g. epibenthic)

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).
