Pomacentrus caeruleus | All sizes

Pomacentrus caeruleus is a visually striking damselfish species prized for its brilliant blue hues and lively behaviour. This species adapts well to captive conditions, making it a suitable addition to a variety of marine aquarium setups.

Temperament and Compatibility: Pomacentrus caeruleus is generally peaceful but can exhibit territorial behaviour, especially in smaller tanks or when kept in high densities. It is best housed with other semi-aggressive or peaceful species. Avoid keeping with very aggressive fish to reduce stress.

Diet: This damselfish is omnivorous and thrives on a varied diet including high-quality flake foods, frozen mysis shrimp, brine shrimp, and marine pellets. Supplementing with algae-based foods will promote optimal health and vibrant colouration.

Tank Requirements: A minimum tank size of 75 litres (approximately 20 gallons) is recommended to provide sufficient swimming space and reduce territorial disputes. Stable water parameters and good filtration are essential for maintaining health.

Care Level: Pomacentrus caeruleus is considered moderately easy to care for, suitable for hobbyists with some marine aquarium experience.

Reef Compatibility: With caution. While generally reef safe, this species may nip at small or delicate invertebrates and corals, so monitoring is advised when introduced to reef tanks.

Additional Notes: Regular water changes and maintaining stable water chemistry will support the wellbeing of Pomacentrus caeruleus. Providing live rock or hiding places can help reduce stress and territorial behaviour.
