Stegastes adustus, the dusky damselfish or scarlet-backed demoiselle, is a damselfish of the family Pomacentridae found at one- to three-meter depths on surging and wavy coral reefs in the Caribbean Sea, the tropical waters of the western Atlantic Ocean, and the Gulf of Mexico.[2]


Adults feed on algae, plants, and detritus. S. adustus exhibits different feeding behaviors between those that live in coral rubble and patch reef habitats.[3]
