The Blue Damselfish (Chrysiptera cyanea) is a species of fish native to coral reefs throughout the Indo-Pacific. It is known for its impressive ability to change colors, going from its brilliant electric blue hue to a near-black shade in order to hide from potential threats. This color change occurs in a matter of seconds and is an important defensive mechanism for the species. Moreover, the Blue Damselfish is also known for its territorial behavior, defending a small area of the reef from other species. These two traits make the species both interesting and important to reef ecosystems.

The Blue Damselfish is a hardy and beautiful species, making it a great choice for any saltwater aquarium. With proper care and a spacious environment, the Blue Damselfish can be a great addition to any aquarium, no matter your experience level. Though it may demonstrate territorial behavior, adding multiple hiding places will help to reduce aggression between inhabitants. Consequently, the Blue Damselfish is a great choice for both beginners and experienced aquarists alike.

The diet of the Blue Damselfish should consist of a variety of fresh and frozen foods, as well as herbivore preparations.
