Subadults live where meals are plentiful: reef holes and cavities in seaward reef surge channels. Adult emperor angelfish live in caves and underneath ledges in the calmer waters of coral reefs. In the wild, these fish swim at depths of 3.3–328.1 feet. There have also been reports of emperor angelfish colonizing the southwestern Mediterranean as an invader species. These fish have also been spotted in Hawaii, Puerto Rico, and Florida, most likely because hobby aquarists release the fish into the water.
