Slender elongate body, dark upper body with a white underside and a thin white stripe along back. Below white stripe, dark colouring breaks into a series of short vertical bars like piano keys. Moves with sinuous swimming motion, often approaching divers. By luck or design, this species is a close mimic of the eastern hulafish and often lives in vicinity of schools of that species.
Max Size: 14 cm
Sea Temperature Range: 15.8-30.4°C
Habitat Generalization Index: 21.07
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: Common (24.7% 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: Few (3 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
