This species is a simultaneous hermaphrodite, possessing both male and female reproductive systems at all times through their lives.

During mating, the 2 partners take turns fertilizing each others eggs.

The Rapa Nui Fairy Basslet (Pseudanthias hangapiko) is the latest new species for Rapa Nui, commonly know as Easter Island, one of the world's most isolated inhabited islands.

Showing a clearly dimorphism, with males being slightly bigger and redish than females, these fishes are tiny, with around 3 to 4.5 cm in length. These fishes were collected at 80 m depth on Hanga Piko, a mesophotic coral ecosystem near the coast of Rapa Nui, hence its name, for the location where it were collected.

This fish is one of four new species that were documented from a pair of  technical dives at a single location in Rapa Nui, as result of a international research collaboration, emphasizing the high number of undescribed species likely still unknown in these deep ecosystems. It is also, the first record of the genus in Rapa Nui, which hosts the second-highest level of endemism in both shallow and deep-water fishes.

The coral grouper, coral hind, coral rock cod, coral cod, coral trout, round-tailed trout, or vermillion seabass (Cephalopholis miniata) is a species of marine ray-finned fish, a grouper in the family Serranidae, which also includes the anthias and sea basses. It is found in the Indo-Pacific in clear water where there are coastal and offshore coral reefs, it prefers exposed rather than protected areas, and is often seen in caves and below ledges at depths of 2 to 150 meters (6.6 to 492.1 ft).
