A Murray-Darling fish, now reduced to a patchy distribution in Northern New South Wales and Southern Queensland. Originally its distribution extended into Northern Victoria where it had been presumed extinct since the 1930's.
Recently re-discovered in the Cardross Lakes (an irrigation drainage basin system) near Mildura in Northern Victoria. NFA (Victoria) and the Australian Conservation Foundation combined forces to fight to save the fish in this system which was drying up due to changes in irrigation practices. To date, some success has been achieved with water being supplied to restore water levels for the 1996/97 summer. The long term survival of this species and the other aquatic faunal assemblage has not yet been assured.
Slow flowing waters among weed where suitable hard objects are available for spawning. Primarily a bottom dweller, rarely swims continuously. Longer distances accomplished by a series of jerky darts. Migrate from deeper water and spend winter in sheltered situations. An ambush predator, lying motionless on bottom until suitable prey approaches. Amazing jumping ability
Elaborate breeding display between sexes, male cleans spawning site and pairs with a gravid female. Eggs deposited in clusters on solid objects such as rocks, wood, broad leafed plants. Male guards and fans eggs.
Small fish, aquatic insects etc.
