I've personally had no luck with aiptasia X, I shut down a coral grow out tank as I couldnt erradicate them. In my display tanks I use peppermint shrimp. I'm pretty convinced that none of mine are the exact species but rather members of the complex, they do seem to keep any from developing. The only otherway that I've had success dealing with them is the burn and destroy route, using a soldering iron and drill or a mini butane torch.
