My copperband never touched any, not even one. My peppermind shrimps don't care for them either.
I tried a huge bottle of AiptasiaX and they go away for a few days but return.
I am now trying berghias nudibranchs but if you go that route you should not have any peppermint shrimps as they will eat the berghia, and any other fish that might eat them. You can introduce the berghias in the evening when wrasses are asleep. The berghias will hide in the liverock and they are nocturnal so they will come out when the wrasses are asleep and eat the aiptasia. It's a slow method of control and the berghias are very fragile so they must be handled with little pipette, not with hands. I put 5 in my 70 gallons tank. They went into the liverock and I did not see them again. That was a week ago. Now I am seing aiptasias disepearing one by one so I know they are there and coming out at night to eat. I am hoping that they will reproduce and thrive in my tank with the tons of aiptasias that I have (enough to feed an army of berghias).
When introducing berghias, you must not put them directly on an aiptasia as the aiptasia will eat the berghia. YOu must put it near by the aiptasia but out of its reach.
Good luck, those are real pests. I still use aiptasia x from time to time to wipe out those little nasty aiptasias that get into my zoanthids colonies and frags. They seem to have a way to find my zoanthids
