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.
