Yarra Pigmy Perch
Other Common Names
Up to 65 mm, largest recorded 75 mm
Vulnerable. Under pressure from habitat alteration. Listed under Victorian Flora and Fauna Guarantee Act.
Usually found in small groups in well vegetated streams or small lakes, sometimes mixed with Nannoperca australis but seems to prefer slightly faster water.
Relatively uncommon, found in both brackish and freshwater in all coastal streams west of the eastern border of Port Phillip Bay, including the Yarra River, to Bool Lagoon in South Australia.
Very similar to other pigmy perches, best distinguished by small mouth and inconspicuous pale vertical bar at the base of the caudal (tail) fin.
Spawning has been recorded in ponds in September and October at water temperatures between 16 and 24°C.
Presumably similar to Nannoperca australis. Aquarium kept specimens adapt readily to mosquito larvae and other invertebrates, with a preference for insect larvae. This species has potential for use for mosquito control.
