Golden Damsel Amblyglyphidodon aureus occurs in the tropical Western Pacific from Andaman Sea and Christmas Island in the Eastern Indian Ocean to Fiji, north to the Ryukyu Islands, south to Rowly Shoals and New Caledonia in a depth range from 3-45m, max. length 13cm.\nJuveniles in small groups are often found among large sea fans. Adults occur in steep outer reef, occasionally in deep lagoons and along channel walls, usually in current prone habitats and where there are abundant gorgonian and long sea-whip corals on which they lay and guard eggs. The species feeds on zooplankton. \nMost of the time, a fish's behavior depends on its species. From time to time it is possible to meet exceptions, like this specimen, a very curious character, not shy at all, who came back looking at the camera many times.\nTriton Bay, West Papua Province, Indonesia, \n3°54'52.0617 S 134°7'21.3867 E at 9m depth
