Copperband Butterflyfish

Copperband Butterflyfish

The Copperband Butterflyfish, Chelmon rostratus is a unique and interesting, as well as useful fish excellent for most aquariums.  They will spend most of their time picking through the rockwork using their long beak to find food.  Aiptasia is a common food source of theirs in the wild, and they will help control this nuisance in the tank.  They are more delicate than most other Butterflyfish and require excellent conditions as well as a solid diet.  They have been known to pick at soft corals, anemones, and feather dusters, so caution should be taken before adding one to your tank.  They are also best kept singly in an (at least) 55-gallon tank.

Physical Description– Copperband Butterflyfish have bright orange-yellow bands running vertically along their body.  They also have a long, narrow nose they use to hunt for food in cracks and crevices. A large black spot adorns their dorsal fin, likely creating the illusion of a large eye used to ward off predators.

Temperament– The Copperband is a peaceful fish towards most other tank inhabitants.  That said, they will be aggressive towards other Copperbands, as well as most any other Butterflyfish.

Size– This fish reaches a length of 8 inches when fully grown. Most sold are around 4 inches in length.

Diet– Copperbands are known to be very finicky eaters and will require several feedings daily as well as a variety of options. Mysis and brine shrimp, bloodworms, and other enriched meaty products are ideal.  If possible, an established colony of amphipods will help satisfy their desire to forage in the rockwork.

Distribution– The Copperband Butterflyfish can be found throughout the Indo-Pacific region.  Ours typically arrive from Bali.
