Amblygobius phalaena, the white-barred goby, is a species of goby native to tropical reefs of the western Pacific Ocean and through the central Indo-Pacific area at depths of from 2 to 20 metres (6.6 to 65.6 ft). This species feeds by taking in mouthfuls of sand and sifting out algae, invertebrates and other organic matter. It can reach a length of 15 centimetres (5.9 in) TL. It is also of minor importance to local commercial fisheries and can also be found in the aquarium trade.
