Tropical Indo-Pacific


Pink translucent body, golden head, faint dark spots on operculum and underside, pinkish fins, tail with dark fin tips, faint vertical line on caudal peduncle. Forms massive aggregations in caves and under ledges during the day. P. dispar (Deep Bullseye) almost identical, but lacking small spots, making these almost impossible to distinguish without a good photograph or specimen. Latter probably only in QLD.


Max Size: 10 cm

Sea Temperature Range: 19.3-30.9°C

Depth: 3-30m

Habitat Generalization Index: 2.33

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: Not Evaluated

Occurrence: Infrequent (2.8% 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 (541 per transect)

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