Copperband butterfly fish are the only ones I know of. However they can pick at feather dusters, anemones, and clams if you ever want those, you would no longer be able to. They are difficult to keep b/c they are such picky eaters and should be for the more advanced hobbyist. They also need a large aquarium..LA says 125 gallons. I wouldn't getting one.
