Good luck with your anemone. I literally had to do a complete rescape just to make sure my anemone stay where I want it to stay. After that, I place the fake live rock around it. During this period, there was minimal amount of coral in the tank. Took my time with the anemone, including acclimatising it to my Maxspect led lightset. When it stayed for 2 weeks, I started to add coral to the tank. Nowadays, the true percula hosting the anemone continue to spawn just behind the anemone. I've tried in total 3 anemone and all perish when they moved into the wavemaker. The 4th looks to be a success. Sorry for the long post.
Hope this helps!
