The Golden Domino Damselfish, also known as the Yellow Domino Damselfish, Threespot or Yellow Dascyllus, is renowned for its unique coloration. It is easily recognized by the three white spots on its yellow and black body, which differentiate it from the standard Domino Damsel. As juveniles, the species may appear quite similar to the standard Domino Damsel, however, as the fish matures, its gold tinting will become more prominent. In the wild, this fish is an active and hardy species that makes a great addition to any aquarium. It is also an excellent choice for beginner aquarists due to its easy maintenance requirements.
A 30 gallon aquarium or larger with plenty of live rock and décor is ideal for housing a group of Golden Domino Damselfish. This fish is a popular choice among beginners due to its tolerance of substandard water parameters. With its vibrant coloration and dramatic behavior, this species will add a stunning visual element to any marine tank. As they mature, they may become territorial so it is important to keep them with other semi-aggressive or aggressive fish. To ensure their health and well-being, regular water parameter testing is essential. Furthermore, providing ample hiding spots will help reduce stress levels.
The Golden Domino Damselfish is an herbivore that feeds on a variety of meaty foods, herbivore preparations, and flaked foods.
