The Fathead anthias is also known as the Sunburst anthias because of the splash of yellow color on its face. It was originally described in 1949 and was placed in the hawkfish family. Its genus means grouper-hawkfish. These hardy aquarium fish generally prefer the protection of an overhang, or cave and can often be seen swimming upside down. Unlike their other anthias cousins, they have a deep body and elongate pectoral fins.
