Copperband Butterflyfish (Chelmon rostratus)
Iconic, Graceful & Highly Sought-After Reef Fish
The Copperband Butterflyfish is one of the most recognisable marine fish in the hobby, featuring its long snout, bold vertical orange bands, and elegant disc-shaped body. Known scientifically as Chelmon rostratus, this species is admired for its beauty, peaceful temperament, and ability to help control nuisance pests such as Aiptasia anemones.
Best suited for mature aquariums, the Copperband Butterfly thrives with stable water conditions, plenty of rockwork, and a varied diet. While often labelled as “reef-safe with caution,” many aquarists successfully keep them in mixed reefs when given adequate feeding and space.

- Iconic orange and white vertical stripes
