Caesio caerulaurea | S

Caesio caerulaurea, commonly known as the Blue and Gold Fusilier, is a striking marine snapper prized for its vivid blue and yellow colouring and active schooling behaviour. This small variant is ideal for marine aquarists seeking a dynamic addition to a suitably sized tank.

Care Level: Moderate to advanced. This species requires stable water parameters and ample swimming space.

Temperament: Generally peaceful but active and fast-moving. Best kept in groups to mimic natural schooling behaviour, which reduces stress and aggression.

Diet: Omnivorous. Feed a varied diet including high-quality marine pellets, frozen mysis shrimp, brine shrimp, and finely chopped seafood. Supplement with algae-based foods to ensure balanced nutrition.

Minimum Tank Size: 300 litres (approximately 80 gallons) to provide sufficient swimming room and maintain water quality.

Reef Safety: With Caution. While not typically aggressive towards corals, they may nip at small invertebrates or sessile animals if stressed or hungry.

Lighting Requirements: Standard marine aquarium lighting is sufficient; no special lighting needs.

Water Flow: Moderate to strong flow to replicate natural reef currents and support health.

Placement: Mid to upper water column swimmers. Provide open swimming areas and avoid overcrowding.

Origin: Indo-Pacific region.

Maximum Size: Up to 30 cm (12 inches) in captivity.

Ensure regular water changes and maintain excellent water quality to support the health and vibrancy of your Caesio caerulaurea. They thrive best in groups of 5 or more to exhibit natural schooling behaviour and reduce stress.
