Just in case you haven't heard it enough yet, I would like to echo the above experiences. If you try to house an anemone with LPS, you will probably not be happy with the compromises you have to make.
I have a LTA in my tank and fully expanded, it takes up about a third of the tank (from side to side) and more than half (from bottom to top). I have to leave a wide margin of nothing of value that it could sting. That is a lot of wasted real estate. I am very fortunate in that it has not let go & rolled around in the current for many years, although it could. It does move a little, but I have it hemmed in with pillars of rock & that limits the movement. If it really wanted to, it could take off & wreak havoc. As a responsble owner, I don't feel like getting rid of it, but if I could do it over again, I wouldn't. My clown fish would be quite content to host in a euphyllia - and they don't move around.
