About

The Domino Damselfish (Dascyllus trimaculatus) is widespread across the Indo-Pacific from the Red Sea and East Africa to the Line and Pitcairn Islands, north to southern Japan and south to Sydney, but absent from Hawaii and the Marquesas. It lives in small to large aggregations on coral and rocky reefs at 0-55 m, and juveniles are commensal with large sea anemones, sea urchins or small coral heads. Juveniles are black with three white spots on the forehead and upper flanks, the source of both the Japanese and English names. With growth the forehead spot disappears, the flank spots shrink and the color varies by region and condition. Maximum length is 14 cm. It feeds on algae, copepods and other planktonic crustaceans, spawns in pairs on the substrate and the male guards the eggs. Very hardy and tolerant of water quality swings, it is considered a beginner's fish, but the cute juvenile grows into a large, aggressive adult. It suits a tank of 114 L or more with large, robust tank mates to grow up alongside. It will take up residence in a carpet anemone (Stichodactyla) if one is present. It does not bother corals or invertebrates.
