Rolland’s Damselfish is also known as the Black Cap Damselfish, and these fishes originate from the South Pacific. They are a beautiful fish colored in yellow, black and white, and are relatively mild mannered for a Damselfish. These fishes will add color and activity to any saltwater community or reef aquarium.A 30 gallon aquarium or larger with plenty of rockwork and décor is ideal. Because it can tolerate less than ideal water parameters, it is a popular fish among beginning hobbyists. A small group of juvenile Black Cap Damsels will add color and drama to most marine aquariums. Maintain this species with other semi-aggressive fish, as they can become territorial as they mature. In larger reef aquariums, this is normally not a problem if plenty of hiding places are provided.
Rolland’s Damselfish feeds on a variety of meaty foods such as frozen mysis or brine shrimp, herbivore preparations, and flaked foods.
