Color
Males are greenish-blue on the upper two-thirds of the body with a dense pattern of fine black spots and irregular vertical lines, a white belly, and dark outer caudal-fin rays making the tail appear deeply forked. Females are pinkish to pale purplish-grey with a silvery-white stripe above and below the eye, and a distinct red spot on the pectoral-fin base.
Etymology
Pseudocoris: Greek, pseudes = false + Greek, kore = pupil.
Distribution
Indo-West Pacific: East Africa, Madagascar, western Mascarenes, Maldives and Chagos Archipelago east to Marshall Islands and Samoa, north to southern Japan, south to Lord Howe Island, New Caledonia and Kermadec Islands.
Biology
Found in lagoon, channel and seaward reefs. Often on open sand flats with large remote bommies. Juveniles congregate on reefs feeding on mysids. Aggregates (with females outnumbering the males) along upper edges of coral slopes to feed on zooplankton. Forms a harem with a dominant male and a group of females. This species is collected for the aquarium trade.
