The Chaetodon Lunula, commonly known as the Raccoon Butterflyfish, is a captivating addition to any marine aquarium. This large butterflyfish is admired for its bold patterns and vibrant colours, making it a standout specimen in a well-maintained reef or fish-only setup.
Care Level: This species is best suited for experienced hobbyists due to its specialised dietary needs and sensitivity to water quality. It requires a minimum tank size of 150 litres to provide ample swimming space and reduce territorial behaviour.
Temperament and Compatibility: Generally semi-aggressive, the Chaetodon Lunula can be territorial, especially towards other butterflyfish or similar-shaped species. It is compatible with larger, non-aggressive tank mates but may not be reef safe as it can nip at corals and invertebrates.
Diet: In the aquarium, this butterflyfish thrives on a varied diet including high-quality frozen mysis shrimp, brine shrimp, and specialised marine fish pellets. Supplementing with algae-based foods can help mimic natural feeding habits.
Water Parameters and Environment: Maintain stable marine conditions with a temperature between 24-27°C, pH 8.1-8.4, and salinity of 1.023-1.025. Moderate water flow and good filtration are essential to keep water quality high.
Placement: Provide plenty of live rock for grazing and hiding spots to reduce stress. Avoid overcrowding to minimise aggression.
With attentive care, the Chaetodon Lunula can become a stunning focal point in your marine aquarium.
