Description

The starry goby is a small goby (family Gobiidae) of the Indo-Pacific. The species reaches about 6 cm and has a stocky, brown-blackish body covered with small blue speckles, which give it its name. It lives on algal-coated reef rock and rubble of inner flats and turbid lagoons and takes refuge in burrows and holes in the reef. Its diet consists of small bottom invertebrates. Because of its small size the species is harmless to humans and of no fishery value, though it is sometimes collected for the reef aquarium.
