I'll be curious to see how these go for you guys.  Will you keep us posted?  I tried peppermints and I think my wrasses killed them.  I have a CBB now and he has eradicated the aiptasia, but they can be a struggle to keep alive long term.  I had the matted filefish that ate Aiptasia...but he turned on corals.  Never tried the Berghias though, I hope they work well for you guys!
