Product Description
The Redfin Butterflyfish (Chaetodon lunulatus) is a stunning marine species recognised for its bright yellow body, fine vertical markings, bold black eye band, and distinctive reddish-orange highlights on its fins. Elegant and active, it brings vibrant colour and graceful movement to larger saltwater aquariums.
This butterflyfish is best suited to experienced marine aquarists, as it requires a mature, stable aquarium and can be challenging to establish on prepared foods. With the right care and environment, it becomes a spectacular display fish.
