HabitatUnlike Southern Pygmy Perch, this species is most common in habitats with high water velocities. Can be found in fresh or slightly brackish waters with dense aquatic vegetation. Usually found over gravel substrates, cobble or boulders in areas without siltation. However, in Ewens Ponds in South Australia it is associated with heavy detritus cover. DistributionOnly recently discovered, this species has been found only in the Ewen Ponds system in South Australia and some tributaries of the Gleneg River in south western Victoria. The presence of trout, redfin and golden perch as major fish predators in the Glenelg River are of concern. ReproductionAdults appear to migrate upstream to spawn, thought to be a multiple spawner like the Southern Pygmy Perch. DietBelieved to be completely carnivorous, feeding on benthic insect larvae and crustaceans. AnglingNot an angling species. On the tableNot a table fish. In the aquariumHas great potential as an aquarium species. Requires well oxygenated water, feed with small shrimps and mosquito larvae. | |
