The Threespot Damselfish is also commonly known as the Domino Damselfish due to it's coloring. It is black with a trio of white spots. 

They are completely reef safe and can live in a community tank with fish with similar temperaments, as they become more aggressive with age and will try to bully other fish. It should be the only member of it's species in the tank. It is a very hardy fish. Being omnivorous, it should be fed both meaty foods and plant matter. It is a ravenous eater and will readily accept live, frozen, flake and pellet foods.
