Alex;

I'm afraid there's not a lot you can do other than try to anticipate where in your tank the anemone will find it's preferred habitat and clear the decks from that area. Typically, they seem to prefer a lower flow, lower light in my tank. It seems critical for them to have a secure spot to disappear into. Since anemones are "hard wired" to seek out specific habitat requirements, you can't train it to be where you want it. Some people have had luck putting it a spot, then feeding it, but not me.

Let me know if you have any corals you need to move, I'll be glad to take 'em! hehe
