Lower silver stripe extends well past operculum on to body.


Max Size: 7 cm

Sea Temperature Range: 22.5-31.4°C

Depth: 0-22m

Habitat Generalization Index: 13.57

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 (32.3% 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 (25 per transect)

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