|Population:||This species is extremely abundant in shallow reef habitats in Galapagos, Cocos, and Malpelo Islands.
In the Galapagos archipelago it had an overall mean abundance of 8.30 ind./500 m2 (Edgar et al. 2004).
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species inhabits coral and rocky reefs (Allen, 1991) to depths of 20m. This fish is omnivorous, feeding primarily on algae and invertebrates including tubeworms, small crustaceans, and the tentacles of anemones (Grove and Lavenberg, 1997).|
|Major Threat(s):||There are no major threats known for this species. In Galapagos, a minor decline in population numbers accompanied the 1997/98 El Niño event, but was followed by a full population recovery within one year.|
|Conservation Actions:||There are no conservation measures known for this species. However, it is present in Marine Protected Areas in Galapagos, Malpelo, Cocos, Machalilla and Gorgona (WDPA 2006).|
