Very common solitary inhabitant of shallow reefs where it cultivates filamentous algae as food.  Vigorously defends this farm against roving herbivores.  Light gray-brown with black scale edges and yellow eyes, juveniles with neon blue fin margins and yellow tail.  Attains 5 inches.  Endemic to Hawai'i.  Formerly known as Stegastes marginatus.  Before that it was confused with Stegastes fasciolatus, which is a Central Pacific species.
