Copperband Butterflyfish (Chelmon Rostratus)


The Copperband Butterflyfish, known as the Beaked Butterflyfish or Orange Striped Butterfly, has a narrow, long snout and mouth used for stalking small prey and food in holes and crevices. This butterfly has orange orange-yellow vertical bands with black margins. On the rear of the dorsal fin, it has a false eyespot. The Copperband Butterfly is unique with its orange bands and no other butterflyfish has these distinct features.


It is best to house it in very large reefs or in peaceful community tanks. It should be kept as a single, not with conspecifics or similar butterflyfish, and it should not be kept with any stress-inducing fish. One should be cautious if housing these fish in a reef aquarium. They may bully invertebrates, especially anemones and feather dusters. If anything, they are the perfect fish to control aiptasia or glass anemone.



The diet of the Copperband Butterflyfish is extensive due to the fact that they are picky eaters. Their diet may include: live worms, clams, shaved mysis, and frozen shrimp. Keep in mind that their mouths are rather small, so their food will have to be chopped finely.
