The vast majority of the species' population occurs at a single location in the Revillagigedo Islands, where it is restricted to reef habitat with an estimated area of occupancy of less than 50 km2. It has previously been collected for the aquarium trade. Regional experts support the plausible threat of the increased duration and frequency of ENSO events that can cause severe and rapid declines for restricted-range, shallow-water species. This species qualifies for Vulnerable under Criterion D2. However, more research is needed on this phenomenon, and this species should be reassessed when new information is available.
