The split-level hogfish, Bodianus mesothorax, is a species of wrasse native to the western Pacific Ocean and the eastern Indian Ocean. They can be found on reefs at depths of 16 to 131 ft, though rarely below 66 ft. Juveniles inhabit caves in the reef. Adults of this species clean other fish by eating parasites on the body of other reef fish.
Its diet consists of frozen mysis, brine shrimp, and other meaty foods, as well dry marine flake and pellet foods.
