Finke River hardyhead
The Finke River hardyhead is a species of fish in the family Atherinidae. It is endemic to the Finke River system in the Northern Territory, where it is widespread in open water or around aquatic vegetation. They occur in a wide range of salinity and pH and in Summer seek refuge in semi-permanent water holes. They are omnivores and feed on small crustaceans, insects, gastropods, polychaete worms, algae and fish eggs. This species shows a wide tolerance to temperature and salinity and is omnivore, probably spawning during warmer months. It was previously mis-identified as Craterocephalus eyresii.
