Temperate Australasia, Tropical Indo-Pacific


Slender silver-blue body, two narrow yellow stripes along body, the lower stripe extending from upper eye to tail base is below lateral line for most of the length of the body, only crossing near tail base, and dark tail tips. Similar P. marri (Bigtail Fusilier) has yellow stripe covering lateral line for most of body length rather than below it. Often schools with other fusiliers.


Max Size: 30 cm

Sea Temperature Range: 20.1-31.2°C

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: Frequent (17.4% 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: Large aggregations (116 per transect)

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