The mountain galaxias (Galaxias olidus) is a species of freshwater galaxiid fish found all over southeast Australia.
G. olidus occupies a vast geographical range from southern Queensland to the Adelaide Hills in South Australia, and while occurring widely in the Murray-Darling river system, are also found in eastern and southern coastal systems. How much of their coastal distribution is due to natural river capture events (although it is certain much of it is) and how much of it may be due to migration is not clear, for many mountain galaxias species have the ability to "climb" natural migration barriers with modified pelvic fin structures.
Within the Murray-Darling system, the mountain galaxias continues the trend of specialisation into upland and lowland habitats, with species found in upland habitats, and the flathead galaxias found in lowland habitats, though G. olidus strays down to the upland/lowland transition zone in some rivers.
