It is an inhabitant of coral reefs, being found in areas that offer a mix of sand patches, rubble, and coral at depths from 1 to 50 m. This species can also be found in the aquarium trade and is popular species for display in public aquaria.

This species can reach 40 cm in total length, though most do not exceed 20 cm. As a juvenile, it is a bright red colour with large, black-margined white spots. As an adult, it has a pink face and fins, with the exception of the tail fin, which is bright yellow. The body is green towards the anterior darkening and decorated with bright blue specks towards the caudal peduncle. The fish also gains a very bright orange anterior when it grows into adulthood, and has a drastically shaded body in the posterior region that is dotted with very bright blue spots ringed with dark blue.
