Description
The Regal Demoiselle is a striking but highly aggressive damselfish native to the Indo-Pacific. It typically displays a dark body with a prominent white spot at the base of its dorsal fin and often a green spot near the eye. This species is known for its territorial nature, which intensifies with age, requiring careful consideration for tankmates.
