    ***Aggression Warning***

    COMMON NAME: Domino Damselfish

    OTHERS: Threespot Dascyllus, Threespot Damsel

    SCIENTIFIC: Dascyllus trimaculatus (Ruppell, 1828)

    ADULT SIZE: 5.5 in (14cm)

    RANGE: Indo-Pacific

    MINIMUM AQUARIUM SIZE: 55 gal. (208L).

    SOCIAL: CAUTION - A very aggressive species. They will become a threat to each other and other fish that are less aggressive or similar in size. Their prescence will make life difficult or impossible for a mild mannered community. They will also populate an anemone if one is present.

    DISTICTIVE CHARACTERISTICS: One of the medium to larger Damsels. A Black rounded fish with a small white spot on both sides with a third white spot on the "forehead".

    DIET: Varied diet, meaty food, as well as mysid and brine shrimp. Feed at least 3 times daily and, ideally, some herbivore flakes and frozen preparations.

    REEF AQUARIUM BEHAVIOR: Ideal reef inhabitant; will not harm invertebrates and this fish will eat some algae.

    CARE IN CAPTIVITY: This fish will tolerate a tank environment that will kill nearly every other fish. Because this fish is so hardy it is a popular fish used to seed a new aquarium. However as this fish matures, which it does very quickly, it will become increasingly aggressive. Adults can be kept in male-female pairs or singly. The ideal tank environment is one of a moderatly aggressive community. Good co-inhabitants include larger dottybacks, angelfish, and puffers.

    PERSONAL NOTE: This fish is gorgeous when it is young and is tempting to the new marine aquarist. Plus they are pushed at times in the hobby. But if tempted, be prepared to deal with a pugnacious and obnoxious fish later on that will live on and on and on. Please use caution selecting this guy. Its not fair to him to be displaced later because the keeper made a bad choice.

    Yep all this is true. Learned the hard way. I would almost say to consider this guy as a species-only tank only, in which case it would do great and look nice with it's almost-all black.
