Clown fish and threespot dascyllus
Habitat

Generally, adults are found in small groups around coral heads or large rocks. Juveniles may be found associated with large sea anemones or sheltering between the spines of diadema sea urchins or branching corals. May be found up to depths of 55 m.
Etymology
Trimaculatus, meaning "three-spotted", refers to the fish's three white spots. This accounts also for the common name "domino".
