Small, but beautiful

Most people are unaware our unique native freshwater fishes. They are mostly small and like to remain inconspicuous to protect themselves from predators. You are much more likely to see an introduced fish, such as gambusia or goldfish in your local stream, than to see a native fish. But that doesn’t mean that the natives are not there. You just have to look a bit harder.

There are 11 species of native freshwater fish in the south-west of Western Australia, and nine of these are found nowhere else in the world (the other two species are also found in eastern Australia). Around Perth, the species we are most likely to see are freshwater cobbler (Tandanus bostocki), western minnow (Galaxias occidentalis), western pygmy perch (Nannoperca vittata) and nightfish (Bostockia porosa).
