Domino Damsel

The 3-Spot Domino Damselfish, also called the Three Spot Damselfish or Threespot Dascyllus, earns its name from three distinctive white spots against a striking black body. Juveniles display vibrant markings that fade as they mature into more aggressive adults. This hardy species tolerates variable water conditions, making it an excellent choice for beginning aquarists. A 30-gallon aquarium or larger provides adequate space. The Domino Damsel grows increasingly active and territorial with age, making it ideal for pairing with larger, compatible tankmates that can hold their own. Given the opportunity, this fish will form a symbiotic relationship with Stichodactyla species (Carpet Anemones), creating a natural partnership in your reef. Feed a varied diet of meaty foods, herbivore preparations, and quality flaked foods to support health and coloration.
