Dark, large scale edges above the lateral line, becoming fainter towards the lower rear portion of the body. Often has purple or blue-green spots on the face and breast, and sometimes may have a dark marking on the upper surface of the tail base. Very similar to A. ternatensis, but has longer, white pelvic fins (in adults). Juveniles may be yellow and look almost identical to A. ternatensis. The latter species is not known from Australia.


Max Size: 10 cm

Sea Temperature Range: 27.9-31°C

Habitat Generalization Index: 1.33

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: Vulnerable

Occurrence: Infrequent (9.7% 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: Many (49 per transect)

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