Chaetodon fasciatus | L

The Chaetodon fasciatus, commonly referred to as the Large Butterflyfish, is a visually captivating species prized for its distinctive black and white vertical bands and vibrant yellow fins. This species is best suited to experienced aquarists due to its specific care requirements and sensitivity.

Temperament and Compatibility: Generally peaceful but can be territorial towards conspecifics or similar-shaped butterflyfish. It is compatible with other non-aggressive tank mates but should not be housed with overly aggressive species. Avoid keeping multiple Chaetodon fasciatus together unless in a very large aquarium.

Diet: Omnivorous with a preference for meaty foods such as mysis shrimp, brine shrimp, and specialised marine fish pellets. Supplement with algae-based foods to ensure a balanced diet. Feeding multiple small meals daily is recommended.

Tank Requirements: A minimum tank size of 180 litres (approximately 50 gallons) is advised to provide ample swimming space and reduce territorial behaviour. The aquarium should be well-established with plenty of live rock for grazing and hiding.

Water Parameters and Environment: Maintain stable marine conditions with temperature between 24-27°C, salinity at 1.023-1.025 specific gravity, and pH 8.1-8.4. Moderate water flow and lighting are suitable, mimicking their natural reef habitat.

Reef Compatibility: With Caution. While not typically destructive to corals, this species may nip at sessile invertebrates or coral polyps, so careful monitoring is essential in reef setups.

Overall, the Large Chaetodon fasciatus is a rewarding species for dedicated marine fish keepers who can provide the necessary environment and diet to support its health and longevity.
