Just to share my encounter with anemone. 6 months ago, I bought a very nice bubble tip, put it in and as what Sani Boyun said it find a place to settle for the first day and it was at just the place I wanted it to be. Very Nice. Second day, when I checked my tank, nearly fainted, the fellow decided to take up a challenge with my wave maker and got grinded into pieces. Quickly did a 50% water changed to prevent excessive nutrient build up. From that onward, very afraid of trying another one until one month later, when I look through my tank, to my suprise I found a piece of bubble tip attached to one of my live rock and was very healthy and nice colour. It was a piece of remain of the anemone that was being grinded and it survived through. They are actually that hardy and the small piece of remains have actually grown to another anemone which still doing good in my tank.
