Similar to A. auranticavus (Ringtail Surgeonfi sh) and A. bariene (Eyespot Surgeonfish), but spot behind eye is yellow. White ring around tail base may be present, but is not a distinguishing feature. Large individuals are often dark and form large schools, and can be very difficult to distinguish from A. auranticavus from a distance. Differs from A. dussumieri by dark, rather than light scute (tail spine).

• IUCN Threat Status: Least Concern
• Occurrence: Frequent (18% 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: Several (7 per transect)
  Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
