Anthias is a genus of colourful fishes in the subfamily Anthiinae. Most species are found at deep reefs in the tropical and subtropical Atlantic, often well below depths reachable to a scuba diver. A single species, A. noeli, is found at deep reefs in the East Pacific. They are red, pink, orange, or yellow, and the largest species reach 29 cm (11 in) in length. They typically occur in groups that feed on zooplankton.
