Orange-spotted sleeper goby

The orange-spotted sleeper goby is a marine goby (family Gobiidae) from the Indo-Pacific. It has an elongated pearly-white body decorated with rows of bright orange spots and dashes, and spends its days sifting mouthfuls of sand to extract tiny invertebrates, an activity that helps keep the substrate clean. It is peaceful and often kept as a bonded pair, which will work a territory of open sand together. It poses no threat to corals or other fish. It requires a mature reef aquarium with a deep bed of fine live sand rich in microfauna, as its constant sifting depletes food quickly; a productive refugium helps sustain it. It feeds on small crustaceans and can be supplemented with mysis and other frozen foods. A secure lid is advised, as startled individuals may jump.
