Description
The Coral Demoiselle is a hardy and attractive damselfish known for its blue-grey body, often with yellow fins and iridescent blue spots. While beautiful, it can be territorial and aggressive, especially towards conspecifics or smaller, more timid fish. It requires a well-established saltwater aquarium with plenty of rockwork for hiding.
