More Info


Restricted to the mid-reaches of the Yalmy River, Serpentine Creek, and the lower Rodger River, partly within the Snowy River National Park, Victoria, at an elevational range of 140-250 m asl. The species is known to only inhabit a 9.0 km stretch of stream.
Inhabits small shallow, clear flowing streams that are partly shaded in a forested catchment - with a mostly cobble substrate. 


IUCN Critically EndangeredASFB Critically Endangered
This species is considered to have been historically more widespread in the Snowy River catchment. Over the past two decades, this catchment has been impacted by recurring droughts and fires, which in turn has affected population densities of the Yalmy Galaxias (Raadik 2019).
In January 2020, extensive bushfires burnt through the known habitat of the Yalmy Galaxias. Heavy rains following the fires may further endanger this species by washing ash, sediment and toxic chemicals into rivers and streams.
