Tropical Indo-Pacific


Five narrow yellow/orange stripes plus distinct half stripe from eye. Similar to O. wassinki and O. properuptus, but distinguished by narrower yellow stripes, particularly those on lower body, and distinguished from O.rubrimacula by lacking red spot at tail base. Inter-spaces between stripes pearly white except for on head where they are iridescent blue.


Max Size: 8 cm

Sea Temperature Range: N/A

Depth: 1-50m

Habitat Generalization Index: 2.69

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).

Conservation and Rarity

IUCN Status: Not Evaluated

Occurrence: Frequent (10.8% 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 (57 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
