I keep copperbanded butterfly fish mainly to demolish aptasia (also they're a cool fish). I have one in the seahorse tank and haven't had aptasia in there since it went in. Started to get a bad aptasia problem in another reef tank so bought another copperbanded butterfly fish for this one. Only problem is they will go for all the tasty stuff first like fan worms etc before moving onto aptasia. This one seems adamant that it won't make a start on the aptasia until its managed to get my coral hermit crab (it doesn't stand a chance!).
