Galaxias supremus, the Kosciuszko galaxias, is a galaxiid of the genus Galaxias , a member of the Mountain Galaxias species complex group of freshwater fish, found in Australia. [3]
Similar to other member of genus Galaxias. Mouth is set low on the relatively long snout and dorsal, pelvic and anal fins are well back along the body. Caudal peduncle short and shallow with the tail fin long at about 20% longer than the caudal peduncle. Dorsal and anal fins short with the anal fin set well back at about 85% from the front of the dorsal fin, the furthest back of all members of the species complex. Maximum recorded length 96 millimetres (3.8 in), commonly 80–85 millimetres (3.1–3.3 in). [3]
Light brown to tan over body and head and generally lighter below the lateral line with the belly even lighter. Base colour overlain by medium to large darker, uneven blotches mostly joining together to form irregular bands, sometimes also overlain with a shading of tiny, closely packed dark grey spots. Occasionally very small black bars are present mixed in with the blotches and spots around the mid body. Gill covers light brown with a medium sized gold patch. Eye small with a golden iris. A thin band of gold spots sometime present on the upper surface between the nape and the dorsal fin. Head covered with a scattering of diffuse gold flecks and the body from behind the pectoral fins to the caudal peduncle has a band of gold to coppery spots concentrated mostly below the lateral line and towards the rear of the fish. [3]
Not well known, reported only from Blue Lake and its tributary Carruthers Creek in the headwaters of the Snowy River system on Mount Kosciuszko within Mount Kosciuszko National Park in New South Wales and at an elevation of 1,900–1,950 metres (6,230–6,400 ft). Changes to the historical distribution are unknown but the presence of alien trout in the upper reaches of the Snowy River and within 2 km of the Blue Lake system is considered to be a restricting factor on G. supremus's range. [3]
The Kosciusko Galaxias is found in cold water in small clear streams and one on-stream lake (Blue Lake). Stream width was 0.6–1.1 metres (2.0–3.6 ft) and depth was 50–60 centimetres (20–24 in). Stream beds consist of bedrock and boulder, through to gravel and sand, the lake bed consists of pebble, gravel and silt. Able to withstand very cold water below 2 °C (36 °F) for lengthy periods. All these waters are covered with snow and ice for long periods of time during winter. Fish have been collected mainly from pools in streams amongst rock, undercut banks and overhanging grasses. In the lake, fish were collected from rocks and small cobble within 2 metres (6.6 ft) of the shore. The species' location and habitat in deeper waters of the lake is unknown. [3]
Confined to freshwater, with an unknown spawning period likely to be late spring to early summer. Adult fish collected in mid March were found to have mid stage gonad development. [3]
Not an angling target due to small size and conservation status.

Kuhlia marginata, the dark-margined flagtail, spotted flagtail, silver flagtail, orange-finned flagtail, northern jungle perch or mountain bass, is a species of diadromous ray-finned fish, a flagtail from the family Kuhliidae. It is found in eastern Asia and Oceania.
Chaetodon falcula, the blackwedged butterflyfish or falcula butterflyfish, is a species of marine ray-finned fish a butterflyfish belonging to the family Chaetodontidae. It is found in the Indian Ocean.
Labeo heladiva, is a species of freshwater fish in the family Cyprinidae. It is endemic to Sri Lanka. Earlier considered as the same species as Labeo dussumieri in India, recent phylogenetic and physiological differences suggest that Sri Lankan population is a distinct species.
