The Maroon Clownfish / Maroon Anemonefish / Spine-Cheeked Anemonefish (Premnas biaculeatus) is a less-common Anemonefish found in the Indo-Pacific region in comparison to other anemonefish species. Its names come from its colouration and/or markings. These also vary depending on location. Like other Anemonefish, they form a symbiotic relationshp with their host anemones and the fish are led by the dominant female, who only breeds with the highest-ranking male. When the female dies, this male changes into the dominant female and another male is promoted to be the highest-ranking/breeding male.
