A 30 gallon aquarium or larger with plenty of rockwork and décor is ideal for keeping Black Cap Damsels as it can tolerate less than ideal water parameters. This makes it a great choice for beginning hobbyists. As they mature, they may become territorial and should be maintained with other semi-aggressive fish. To prevent any aggressive behavior, make sure to provide plenty of hiding places in larger reef aquariums. Adding a small group of juvenile Black Cap Damsels will create a vibrant and dynamic aesthetic in most marine aquariums.
Rolland’s Damselfish is an excellent choice for all aquariums and is a hardy species that adapts to a wide range of aquarium conditions. It is important to provide a variety of food sources for this species as it is an omnivore. Rolland’s Damselfish will accept a wide variety of food sources including frozen mysis or brine shrimp, herbivore preparations, and flaked foods. Furthermore, it is important to feed this species small amounts multiple times a day to ensure proper nutrition. It is also beneficial to provide a vitamin enriched food once or twice a week for optimal health.
This size range is great for most applications.
