Edgbaston Goby
(Chlamydogobius squamigenus)
Beneath some of our country's driest and most remote regions lies the Great Artesian Basin, a vast subterranean reservoir stretching through Queensland, the Northern Territory, New South Wales, and South Australia.
On Edgbaston Reserve, it nourishes what scientists have called the most significant natural springs for global biodiversity in the entire Great Artesian Basin and one of the most important in the world. Chances are you're not familiar with the critically endangered Edgbaston Goby, found in just a handful of artesian springs and standing as one of Australia’s most endangered fish.
Gobies grow to about 6cm at most. During courtship, males extend their fins and dance around their chosen nest site. Male Edgbaston Gobies select spots for females to lay eggs, often in caves beneath rocks or vegetation. Males guard the eggs until they hatch. The hatchlings occupy the very shallowest parts of the springs until big enough to compete for space with the adults in the population.
Invasive Mosquito Fish (Gambusia holbooki), feral pigs, and threats to the quality and quantity of water in the Great Artesian Basin are their primary threats.
