Care
Marginate Dascyllus are resilient fish that can adapt to a variety of aquarium conditions. They thrive in well-established tanks with plenty of live rock for shelter and territories. These fish are omnivores and will accept a wide range of foods, including frozen, flake, and live offerings. However, a balanced diet will promote their health and vibrant coloration.
Reproduction
Like many damselfish, Marginate Dascyllus are known to be territorial and may become aggressive during breeding. They lay their eggs on flat surfaces, often in the crevices of live rock. The male guards the eggs until they hatch, which typically occurs after several days.
Habitat
Marginate Dascyllus are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They prefer shallow, coral-rich environments and are often observed in groups hovering above branching corals or within staghorn coral thickets.
