How to add an anemone safely in a reef tank

[Timbits]

Hey guys

I wanna get an anemone probably a bubble tip but I am up for suggestions as long as they are clown hosting anemones. The problem that I have which I'm sure many many others have also ran into this problem is that I'm scared the anemone will start walking which it probably will and kill all my corals. My tank is packed with corals all over the sandbed and sps all over the rocks.

Are there any clown hosting anemones that are less likely to move?
Any tips or tricks? Please share your experiences

Thanks!
