While they are generally peaceful, Blue Damselfish can exhibit territorial behavior, especially towards their own kind or similar species. It is best to keep them in groups of at least three to reduce aggression among them. Suitable tank mates include various reef-safe fish species that occupy different swimming levels.
Blue Damselfish have a diverse diet and benefit from regular, varied feeding. Offer a mix of high-quality flakes, pellets, and frozen foods to ensure they receive essential nutrients. They are grazers and will also enjoy algae growth in the aquarium.
In captivity, Blue Damselfish can live for several years, often exceeding 5 years with proper care. They typically reach a size of about 7.5 cm when fully grown.
The Blue Damselfish is a striking and hardy species well-suited for marine aquariums. With the right care and tank conditions, they can thrive and add a vibrant touch to your aquatic environment.

Introduce Blue Damselfish to the tank gradually to reduce stress and prevent aggression.
Keep water temperature between 22.2-25.6°C (72-78°F), pH 8.1-8.4, salinity 1.020-1.025, and water hardness 8-12 dKH.
Feed Blue Damselfish a balanced diet of live, frozen, freeze-dried, and vitamin-enriched foods such as brine shrimp, finely chopped mysis shrimp, and prepared pellets and flakes.
Be cautious with tankmates, as Blue Damselfish can be aggressive, especially towards similar-sized fish.
