The Paddletail has a forked caudal fin with rounded lobes. It has a pinkish-grey to red body. The fins are red to dark brown. The soft dorsal, anal and caudal fins have white margins. The iris of the eye is red. Juveniles look similar to the adults, but are dark brown to black on the soft portion of the dorsal fin, the caudal peduncle and the caudal fin. In very small individuals, there is a dark stripe below the soft portion of the dorsal fin and a black spot on the caudal peduncle.
The species grows to 50 cm in length.
The species occurs in tropical marine waters of the Indo-Pacific, from the Red Sea, throughout Micronesia, north to Japan, south to Australia, and east to the Tuamoto Islands. In Australia it is known from the north-western coast of Western Australia, and from the northern Great Barrier Reef, Queensland. Juveniles are found south to the central coast of New South Wales.
