Cooper's anthias

The Cooper's anthias (Pseudanthias cooperi) is a marine fish characterized by its vibrant coloration, with males displaying a red to pink body, yellow on the back and dorsal fin, and a distinctive blue line across the head. Females are usually reddish with less distinctive markings. This species is indigenous to the western Indian Ocean, extending from the Red Sea to South Africa. It has a streamlined body typical of anthias, with a size reaching up to about 12 cm (4.7 inches) in length. Although not the most common species in the aquarium trade, it is known among hobbyists for its striking colors and dynamic schooling behavior in nature, making it a sought-after species for those with larger, well-established reef tanks.
