Fish

Galaxiella Billabong was constructed in 1981 with the aim of reintroducing the endangered Dwarf Galaxias (Galaxiella pusilla). The first Galaxia placed in the pond came from a successful breeding program. The endangered Galaxia are now thriving and have spread to other water bodies throughout the Wildlife Sanctuary.

One fish species that we have within the Wildlife Sanctuary that we would rather not have, are Mosquito Fish (Gambusia holbrooki). Initially introduced to Australia in 1925 to control mosquito populations, this species has spread rapidly and has had a significant impact of native fish, frogs and invertebrates.
