This may cause a re-evaluation of the spotted galaxias specimens occasionally recovered in the Murray-Darling river system, which until now were assumed to be accidental translocations via the Snowy Mountains Hydro-Electric Scheme.

They prefer cool, flowing rivers in forested catchments with excellent riparian vegetation, good water quality and cover in the form of boulders, sunken logs and overhanging banks.

[2] Larvae are swept out to sea and return and migrate back up rivers as early-stage juveniles which initially do not resemble adult fish.

In Tasmanian rivers spotted galaxias numbers are severely depressed when exotic trout species are present (Ault & White, 1994).

Galaxias populations in such situations tend to display lower than normal growth, size and fecundity, raising concerns for their long-term future (McDowall, 2006).

A lack of exotic-trout-free habitat reserved for spotted galaxias and other native fish species in south-eastern Australia generally is a major concern.
