This species has a relatively restricted distribution in the east-central and north-western Pacific Ocean, being found only around the Hawaiian Islands Chain. Although there is no evidence for any population declines, the species is taken in the marine aquarium fish trade. However, more than two thirds of its range is enclosed by the Papahanaumokuakea Marine National Monument. This species is therefore listed as Least Concern.

Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This species occurs in insular coastal waters around rocky and coral reefs, and particularly around seaward coral reefs to depths of 136 m.

It is carnivorous, feeding mainly on benthic macro-invertebrates (Masuda and Allen 1993). It has pronounced sexual colour dimorphism and is probably a protogynous hermaphrodite. A single male is usually found together with a group of females (Lieske and Myers 1994).
Systems: Marine

Use and Trade [top]

Use and Trade: This species is taken and traded as an aquarium display species.

Threats [top]

Major Threat(s): There are no known major threats to this species, although specimens are occasionally captured for the marine aquarium fish trade. It is one of the most popular Anampses species in the aquarium trade (Rocha pers. comm. 2009).

Conservation Actions [top]

Conservation Actions: There are no specific conservation measures in place for this species, however, more than two thirds of its range is enclosed by the Papahanaumokuakea Marine National Monument in the northwestern part of the Hawaiian islands. This is a federally regulated no-take reserve that, while not monitored efficiently, is very remote and difficult to get to.
