Common name: Copperband butterflyfish

General information

The Copperband Butterflyfish, also known as the Beaked Coral Fish, is a striking species with bold bands of white and copper-orange, accented by a black-edged eye band and a distinctive elongated snout. This species is scientifically known as Chelmon rostratus and is a popular choice among aquarists due to its beauty and unique feeding habits.

Care

Copperband Butterflyfish are known for their specialized diets and can be challenging to keep in captivity. They require a well-established aquarium with plenty of live rock to graze on and hide among. These fish are best suited for experienced aquarists who can meet their dietary needs, which include a variety of small invertebrates and meaty foods like mysis shrimp, brine shrimp, and clams on the half shell.

Reproduction

In the wild, Copperband Butterflyfish form monogamous pairs during breeding season. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. Raising the larvae in captivity is complex and not commonly achieved by hobbyists.

Symbiosis

While not known for a specific symbiotic relationship, Copperband Butterflyfish play a role in controlling Aiptasia, a pest anemone in reef aquariums. Their natural diet includes these anemones, making them a biological control method for managing Aiptasia outbreaks.

Habitat

C. rostratus is found in the Indo-Pacific region, from the Andaman Sea to Australia and Japan. They inhabit coral reefs and lagoons, often seen at depths of 1 to 25 meters. Their elongated snout is adapted for picking food out of crevices in the coral reef.
