As Rick stated, Copperbands have a pretty bad record in captivity-- it is possible to get a good one and I've kept a few over the years for several years-- but most perish even if they are eating prepared foods. A far better option for aiptasia control is the bristle tail filefish, which will eat aiptasia with gusto. Some of them are model citizens and some will start to pick on things you care about-- particularly zoanthids. The Berghia work for sure, but you need a fair number of them and they are at risk of becoming powerhead slurry.

Wrasses are you best bet for bristleworms or some of the larger more robust butterflys but most of them aren't exactly reef safe.
