How to add an anemone safely in a reef tank

[intarsiabox]

I had RBTA for about six months. It would stay put for about a month and then go into a small power head. I would place the now smaller anemone back into the rocks and the cycle would repeat month after month. After the last time there just wasn't enough of the anemone left and that was the last time I ever put one in my tank. I will admit that it was about the most indestructible coral (I know, some say it's technically not a coral) I have ever seen but it was a PITA.
