We see many of these beautiful fish at Kahalu'u.
These fast-moving wrasses inhabit shallow reefs, often in the surge zone, where they feed mostly on crabs and molluscs. Terminal males have bright ladderlike blue-green markings on a reddish body. The brown and green initial phase adults (both sexes) are smaller and drab by comparison.
At night these fish sometimes sleep in tide pools just above the water line where they can be discovered by flashlight. Juveniles occur in tide pools.
The female has greenish body with irregular rows of brown spots and stripes.
