The Copperband Butterfly is one of the most exotic yet inexpensive fishes, and is considered as a much sought-after fish amongst aquarists in the United States. It actively eats aiptasia. It requires a minimum 40 Gallon tank in which it can spend most of its time inspecting every nook and cranny with its elongated mouth. The Copperband Butterfly might nip large polyps stony corals or clam mantles, and also feeds on feather dusters, and small worms, therefore the copperband butterfly fish is not really considered as reef safe. Due to the petite size of its mouth, the Copperband Butterfly can grab only small particles. It should be fed with a variety of other foods that include Mysis shrimp, raw shrimp, live brine shrimp, and frozen brine shrimp, which serves as a very healthy source of nutrition to the Copperband Butterfly. It is not an aggressive feeder at first, and thus should not be housed with aggressive tank mates. They are susceptible to typical saltwater fish diseases and you need to take proper precautions by using a quarantine tank before introducing them into your main tank. It is very difficult to distinguish male from female Copperband Butterfly and also makes it hard to breed in captivity. It thrives well in a temperature range of 75-82 degree Fahrenheit, with 8.1-8.4 pH, and can live up to 4 years or longer.
