| Family: | Atherinidae (Silversides), subfamily: Craterocephalinae | |||
| Max. size: | 5.5 cm SL (male/unsexed) | |||
| Environment: | benthopelagic; freshwater | |||
| Distribution: | Oceania: New South Wales, Australia. | |||
| Diagnosis: | ||||
| Biology: | 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 C. amniculus but could prove to be a separate undescribed species. Formerly mis-identified as C. eyresii (Ref. 44894). | |||
