is a popular damsel species noted for its white spots on a black body. The distinctive "domino" appearance in juveniles may change as they mature, with the white spots becoming smaller. Its hardy nature makes it a common choice for marine aquariums.

While relatively calm when young, it can become quite territorial and aggressive as it grows. Especially in smaller aquariums, it may disturb other peaceful species. It enjoys establishing territories among rock formations.
