Three Spot Damselfish
Veterinary & Aquatic Services Department, Drs. Foster & Smith, Inc.

The Three Spot Damselfish, also known as the 3-Spot Domino Damselfish, Threespot Dascyllus, or Domino Damselfish, is so named due to the three white spots on its black body. There is also a golden variety of this fish which has a yellow and black body, with three white spots. It matures into an aggressive adult whose bright spots fade with age and will enter into a relationship with Stichodactyla species (Carpet Anemone) if one is available.

A 30 gallon aquarium or larger is suitable in size. Because it can tolerate substandard water parameters, it is a popular fish used for conditioning new aquariums.

The 3-Spot Domino Damselfish feeds on a variety of meaty foods, herbivore preparations, and flaked foods.

Like other damselfish, they are generally compatible with: Dwarf Angelfish, Large Angelfish, Anthias, Basslets, Blennies, Boxfish, Clownfish, Goatfish, Gobies, Hawkfish, Hogfish, Parrotfish, Pseudochromis, Puffers, Tangs & Surgeons and Wrasse.
