[3] The threespot chromis is usually dark gray or black with three white spots: one above, one below, and one on the bottom of the tail.

During spawning season, the male species tend to lighten their bodies while their fins are dark, resembling a pattern of Hawaiian Dascyllus.

To care for these fishes, they should be given wide-open swimming areas.

The threespot chromis is locally common along ledges where they're exposed to the current where it feeds on zooplankton.

The threespot chromis can be displayed in a commercial aquarium.
