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.

• Max Size: 12 cm
• Sea Temperature Range: 20.3-31.3°C
• Depth: 1-25m
• Habitat: Coral Reef
• Habitat Generalisation Index: 17.5
  Also referred to as the SGI (Species generalisation index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

• IUCN Threat Status: Least Concern
• Occurrence: Common (25% of sites)
  Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
• Abundance: Many (15 per transect)
  Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
