Six faint, narrow dark bars that are difficult to discern towards rear of body. Dark pointed dorsal and anal fin and tail. Juveniles have a scissor-tail, like A. sexfasciatus, but differ by not having light margins outside the black tail markings, as well as by having dark margins on rear dorsal and anal fins. Usually found in large schools, feeding on plankton and algae in the mid water above shallow reef crests.

• Max Size: 14 cm
• Sea Temperature Range: 19.0-29.9°C
• Depth: 1-5m
• Habitat: Coral Reef, Rocky Reef
• Habitat Generalisation Index: 9.1
  Also referred to as the SGI (Species generalisation index), this describes the habitat niche breadth of the species.

• IUCN Threat Status: Not Evaluated
• Occurrence: Frequent (13% 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 (21 per transect)
  Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
