Life Cycle Juvenile Adult

Size Small/Medium (5.1-7.6 cm) Medium (10.2-12.7 cm)

The Formosa Wrasse (Coris formosa), also known as the Queen Coris Wrasse, is a bold and active marine species ideal for large Fish Only With Live Rock (FOWLR) aquariums. It displays a dramatic transformation as it matures, shifting from a bright orange-red juvenile with white spots to an impressive adult featuring a silvery-gray body with vibrant facial markings and red-orange fins.

Reaching up to 50–60 cm in length, this powerful carnivore requires an expansive system with a deep, fine sandbed of 10.2–15.2 cm for natural burrowing and sleeping habits. Due to its predatory nature, rock-turning behavior, and appetite for invertebrates, it should be housed exclusively with large, aggressive tankmates in an aquarium secured with a tight-fitting lid.
