About Stegastes acapulcoensis (Fowler, 1944)
Stegastes acapulcoensis, commonly known as the Acapulco major, Acapulco damselfish, or Acapulco gregory, is a species of damselfish belonging to the family Pomacentridae. It is native to the tropical and subtropical eastern Pacific Ocean. Its geographic range stretches from Baja California, Mexico, south to the Cocos Islands, the Galapagos Islands, and Lobos de Afuera Island in Peru's Lambayeque Region. This species occurs on or near reefs at depths down to approximately 16 meters (52 feet). It is most often found over sandy seabeds and in tide pools, but can also sometimes be found in rocky or coralline habitats. Stegastes acapulcoensis feeds on algae, and it farms and guards the algae it grows within its own territory.
