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
