The Regal Damsel is a two-tone, darting marine fish its front portion of the body is bright blue. The posterior portion, anal fin, and tail are yellow. There is a species variation in the amount of yellow on the body of the fish.
An aquarium with plenty of rockwork and décor is ideal. Because it can tolerate substandard water parameters, it is a popular fish among beginning hobbyists. A small group of juvenile Regal Damsels will add colour 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.
The Regal Damsel diet should consist of quality flake foods, frozen meaty foods such as brine or mysis shrimp and occasionally dried seaweed offered on a feeding clip.
