The pastel-green wrasse, Halichoeres chloropterus, is a species of wrasse native to the central western Pacific Ocean. It can be found on coral reefs and the surrounding areas at depths from the surface to 10 m (33 ft). Its coloration varies depending upon the habitat in which it occurs, ranging from bright green in fish living in areas with heavy algal growth to pale or with dark bars for those inhabiting rubble areas. This species can reach 19 cm (7.5 in) in standard length. It is of minor importance to local commercial fisheries and can be found in the aquarium trade.
