I've been having aiptasia completely taking over my tank for a while now. I have tried several different methods to remove them, (peppermint shrimp, Aiptasia-X, lemon juice...) and nothing has really worked. In fact the chemical approach has made it worse if anything. I had read about the Berghia online at Salty Underground but kind of forgot about them until I read this thread. I ordered 6 for my 55 gal. reef tank today. With the holidays I'm not sure when they will arrive, but the sooner the better! I will try to take some before and after pics to see how well they work. I like the idea of giving them away to someone else that needs to rid their tank and not just let them die off when the aiptasia are gone. I'll post the pics, probably in a new thread, in a few months once the aiptasia are gone and see if anyone needs them for their tank.
