​The Shannon paragalaxias is a Tasmanian endemic freshwater fish. It is a small fish reaching about 75mm in length and varies in colour from almost black to greeny-brown on the back with vague bands and spots down the sides. It has a lighter coloured underside. It occurs only in Great Lake, Shannon Lagoon and Penstock Lagoon on the Central Plateau. It occurs around the rocky margins of Great Lake and in beds of vegetation in Penstock Lagoon. The species eats insect larvae and other small animals.
Threats are from habitat quality issues from water level fluctuations and the possibility of hybridisation with other galaxids introduced through interconnected waterways both caused by hydro-electricity production. Predation from exotic fish species is also a significant threat.

Permit: A permit is required under the Tasmanian Threatened Species Protection Act 1995 to 'take' (which includes kill, injure, catch, damage, destroy and collect), keep, trade in or process any specimen or products of a listed species. Additional permits may also be required under other Acts or regulations to take, disturb or interfere with any form of wildlife or its products, (e.g. dens, nests, bones). This may also depend on the tenure of the land and other agreements relating to its management. ​​​​​
