IUCN Red List Status: Least Concern (LC)

Dorsal spines: 11; Dorsal rays: 15-17; Anal spines: 3; Anal rays: 8.

Pale orange red to bright red fish with contrasting dark and light red bars on the back and flanks (5 to 6 dark bars the last on the peduncle). Distinctive black membrane between dorsal spines.

Habitat and Ecology:

Reef associated, common on outer reef slopes (depth range 4-160m, but usually 20-45m). Also occurs in protected bays. In Seychelles, it was commonly seen resting in open rocky areas than in dense coral areas (Howlett et al 2016).  Feeds on fish, shrimp, crabs and octopus. Recorded to form spawning aggregations. Exhibits a combination of simultaneous and sequential hermaphroditism. Smaller individuals within a social group are simultaneous hermaphrodites, while the largest often lose female function and reproduce exclusively as a male.


Fishery Status:

This species is not protected or subject to fishery regulations. It is caught primarily in the hand line fishery but also occurs in the trap fishery.  It is a frequent though not particularly abundant component of the catch.
