This fish was first described in 1987.[2] It has been found in variety of habitats, brackish pools or flowing to turgid waters, in the Upper Roe River and one of its tributaries. The distribution range is within the Prince Regent National Park (formerly the Prince Regent Nature Reserve).[3] Little is known about the biology or ecology of the freckled hardyhead, but it is an omnivore.[4]


The species was assessed as near threatened on the 1996 Red List, and in need of reassessment in 2008.[1] It is listed as rare under the Australian Environment Protection and Biodiversity Conservation Act 1999 and as lower rish by the Australian Society for Fish Biology.[4]
