The Chrysiptera cyanea, commonly known as the Blue Damselfish, is a popular choice for marine aquarists seeking a splash of vivid colour and lively behaviour. This tank-bred variety ensures hardiness and acclimatisation to aquarium life, making it suitable for hobbyists of all levels.
Appearance: Featuring a striking electric blue body, the Blue Damselfish adds a vibrant focal point to any reef or marine tank.
Temperament and Compatibility: While generally hardy, Chrysiptera cyanea can exhibit territorial behaviour, especially in smaller tanks or when kept with similarly sized or aggressive species. It is best housed with other semi-aggressive or peaceful fish. Avoid keeping multiple males together unless the tank is spacious.
Diet: An omnivorous feeder, this species thrives on a varied diet including high-quality flake, pellet foods, frozen mysis shrimp, and marine algae. Regular feeding 1-2 times daily supports optimal health.
Tank Requirements: A minimum tank size of 75 litres (approximately 20 gallons) is recommended to provide adequate swimming space and reduce territorial disputes. Stable water parameters with temperatures between 24-27°C, salinity of 1.020-1.025 SG, and good filtration are essential.
Reef Compatibility: Chrysiptera cyanea is generally considered reef safe with caution. It may nip at soft corals or small invertebrates, so monitoring is advised when introduced to reef systems.
Choose from various sizes to suit your aquarium setup and stocking preferences. Our tank-bred specimens ensure robust health and acclimatisation, supporting sustainable marine aquarium keeping.
