Description
Males green with numerous stripes along the body, broken by a series of short bars on the back, and with yellow and black pectoral fin base. Females and juveniles with fine pinstripes, two ocelli on dorsal fin (which disappear with age), and one on upper tail base. Very common. Indian Ocean populations from western Indonesia to the Maldives considered a separate species (H. chrysotaenia), with spots on the tail of males, but this is not yet reflected in global databases.
