FBname: Darling river hardyhead
Comments: Inhabits slow-flowing, clear waters of small creeks and streams; usually in the shallows or at the surface, often among aquatic vegetation (Ref. 44894).  Found in rivers (Ref. 26703).  Solitary or in small aggregations of 10-15 fish.  Spawning possibly occurs in late to mid summer as indicated by the capture of sub-adults in September.  The upper Hunter river (New South Wales) has yielded specimens of a similar hardyhead which are tentatively identified as <i>C. amniculus</i> but could prove to be a separate undescribed species.  Formerly mis-identified as <i>C. eyresii</i> (Ref. 44894).
