Description
The Violet Demoiselle is a vibrant damselfish characterized by its dark body and striking yellow caudal peduncle and tail, often with blue or violet fin edges. Found in the Indo-Pacific, this species is known for its territorial behavior, especially as it matures. It requires a well-established saltwater aquarium with plenty of rockwork for hiding and claiming territory.
