Holacanthus, from Ancient Greek ὅλος (hólos), meaning "full", and ἄκανθα (ákantha), meaning "spine", is a genus of marine angelfishes (family Pomacanthidae). The eight species are particularly abundant near volcanic rocks and coral islands. Some are highly valued as food, but even more so for aquaria, as all are brightly colored.
