Morphology | Morphometrics
Oceania: river systems east of the Great Dividing Range of Queensland, Australia from the vicinity of Gladstone (Boyne River) north to the eastern watershed of Cape York Peninsula.
Inhabits streams and lakes, often forming large schools at the surface. Temperatures in their environments range from 20 to 29 °C and pH from 5.3 to 8.5 and the water varies from clear to turbid (Ref. 7298).
Females attach their eggs to aquatic vegetation and other submerged materials, e.g. Melaleuca sp. roots found in banks and margins of rivers (Ref. 35356). Distinct pairing (Ref. 205).
