Galaxias aequipinnis, the East Gippsland galaxias, is a galaxiid of the genus Galaxias , a member of the Mountain galaxias species complex group of freshwater fish, found in Australia. [1] [2]
A long tubular fish to 110 millimetres (4.3 in) in length, commonly 70–80 millimetres (2.8–3.1 in). Compared to other members of the G. olidus species complex G. aequipinnis is somewhat stout with a long head and snout. The lower jaw is shorter than the upper. Colour is brown on the sides of the head and snout extending to the upper surfaces and on the sides above the lateral line becoming lighter to cream on the lower sides and silvery white on the belly. Sides overlain with dark irregular marks, with some more or less joining together to form uneven vertical bands. [2]
With a very restricted range, G. aequipinnis has been found at elevations of 250–390 metres (820–1,280 ft) AMSL in the Arte River and Little Arte River which are tributaries of the Goolengook River within the Bemm River catchment in East Gippsland. [2]
Small to moderate freshwater streams, 1.5–6.0 metres (4.9–19.7 ft) width and 150–400 millimetres (5.9–15.7 in) in depth, within heavily vegetated catchments, consisting of cool and clear to slightly tannin-stained water. Substrate is mostly bedrock with boulder and smaller rounded rocks as well as small amounts of gravel and coarse sand and larger areas of silt. Instream cover is mostly rock, overhanging vegetation and woody debris, with only smaller areas of macrophytes. [2]
A purely freshwater fish and unlike some members of the Galaxias family is not believed to undertake downstream migration to the sea as part of its lifecycle. Running ripe male and females with ovaries at an advanced stage of development have been collected in late May. However, to confuse the issue, some immature fish have also been collected in May indicating a possible late spawning with a hatching around the previous November or December. [2]
This species is totally protected and is listed under the Victorian Flora and Fauna Guarantee Act, it is not an angling target [3] [4]

The Tasmanian mudfish, Neochanna cleaveri, is a small Australian amphidromous fish in the galaxiid family, of the order Osmeriformes.
Galaxias is a genus of small freshwater fish in the family Galaxiidae, and are frequently referred to as the galaxiids. These highly adaptable fish are typically found at temperate latitudes across the Southern Hemisphere.
The Cathedral Range State Park located in Victoria, Australia, approximately 100 kilometres (62 mi) north-east of Melbourne. It is situated between the towns of Buxton and Taggerty and runs parallel to the Maroondah Highway. The Cathedral Range was declared a State Park on 26 April 1979. It consists of 3,577 hectares and contains the rugged Razorback and spectacular peaks of the Cathedral Range, Little River and forested hills of the Blue Range. Due to its proximity to Melbourne the Cathedral Ranges are a popular destination for both day and weekend adventures. Bushwalking, camping, rock climbing and abseiling are some of the more popular activities available. Cathedral Range State Park is listed as Category II under the IUCN World Commission on Protected Areas and is an example of a park that can be used for recreation, education and conserving natural ecosystems.
The Blue Lake is one of only four cirque lakes found in mainland Australia. The other three, Cootapatamba, Albina, and Club, are shallower and are held entirely by terminal moraines. Blue Lake's valley contains the best-developed glacial features in the Kosciuszko National Park alpine area of New South Wales. It was recognised as a wetland of international importance on 17 March 1996 when a 320-hectare (790-acre) area, comprising the lake and its surrounds, including nearby Hedley Tarn, was designated Ramsar Site 800 under the Ramsar Convention on wetlands. The lake lies within the Australian Alps National Parks and Reserves.
