These fish cannot easily be sexed visually and can change sex and are hermaphroditic by nature. Males usually care for the eggs after spawning and these fish have been bred in captivity.

Tank compatibility[edit]

Although relatively peaceful while juvenile, once they mature, they are quiet aggressive fish and should therefore only be kept one to a tank. It can be aggressive towards any other fish tank mates, even those much larger than itself, and is not suitable for a community set up. They are generally not a threat towards corals and invertebrates.


The Jewel Damsel will take a variety of meaty and veggie foods including mysid shrimp, brine shrimp and spirulina as well as flake and pellet food.

Feeding regime[edit]

Feed once or twice a day.

Environment specifics[edit]

These fish must have a spacious tank with plenty of hiding spaces as well as swimming space and they are sensitive to water quality issues.


An aggressive and territorial fish.


When these fish are juvenile they are dark blue/black in base colour with many lighter blue spots. As they mature the spots fade, and may disappear completely, and they will often develop a bright yellow caudal fin.
