Species of fish
Melanotaenia australis, the western rainbowfish, is a species of freshwater rainbowfish endemic to Australia's Kimberley and Pilbara,[1] Top End.[2] The western rainbowfish (Melanotaenia, australis) is one of the most common and highly abundant freshwater fish endemic to north-western Australia;[3] It ranges from the Ashburton River in the Pilbara region of Western Australia to the Adelaide river in the Northern Territory.[4] It shows extensive geographic variation in their color pattern.[3]
Predation is associated with the variation in color pattern in rainbow fish ( Melanotaenia australis).[5] Meanwhile, variation in reflectance and body shape was associated with variation in environmental conditions.[5]
