The females are inconspicuously colored gray to gray-olive, only the front dorsal fin is blue. Australian desert gobies grow to be six inches long.

Way of life

The fish prefer to stay in shady areas of their home waters that are structured by plants and stones. They form territories, the males are incompatible with each other. Australian gobies feed on insects, their larvae, small crustaceans, detritus and fine algae. Like most gobies, they spawn in caves dug under stones, and the brood is guarded by the male until hatching after five to seven days. The young gobies are fully grown when they are six to eight months old.
