The threespot dascyllus (Dascyllus trimaculatus), also known as the domino damsel or simply domino, is a species of damselfish from the family Pomacentridae. It is native to the Indo-Pacific from the Red Sea and East Africa, to the Pitcairn Islands, southern Japan, and Australia, and can also be found in some parts of the Philippines.[2] Its grey to black body has two lateral white spots and one between the eyes like domino hence the name; the threespot dascyllus grows up to 13 cm in length. Coloration is somewhat changing; the spot on the forehead may be gone and the side spots very much smaller. It feeds on algae, copepods and other planktonic crustaceans.[3]

Living area

[change | change source]

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.[4] This species may be found to depths of 55 m.

Name meaning

[change | change source]

Trimaculatus, meaning "three-spotted", refers to the fish's three white spots. This accounts also for the common name "domino".[5]

In aquarium

[change | change source]

During the juvenile period, they live with the sea anemone. They grow fast and can grow up to 14 cm in length in a large fish tank. People who like big fish may raise a pair of small Threespot to observe their growth.[6]
