Summary:
A small black and white-striped wrasse found in coral rich areas on shallow protected reefs.
Adults are white with a broad black midlateral stripe from the snout to the tail base, and another dark somewhat less distinct stripe below the dorsal-fin base, and a yellow tail. Small juveniles have three broad black stripes and a black tail. The lower stripe disappears with age and the tail becomes yellow.
Yellowtail wrasse have thick fleshy lips. The juveniles "clean" parasites from other fishes, while the adults feed on coral polyps.
