About this species
Cirrhilabrus ryukyuensis is a wrasse from the western Pacific Ocean from Indonesia, Malaysia and the Philippines north to Japan. It occasionally makes its way into the aquarium trade. It grows to a size of 15 cm (5.9 in) in length. Some authorities regard this taxon as a synonym of Cirrhilabrus cyanopleura, but FishBase and the Catalog of Fishes treat it as a valid species. This species was at times called Cirrhilabrus lyukyuensis, but this is treated as a misspelling.
