Everyone has given good advice here... I learned with my first tank to add the anenome, and give it a week, or so to find the spot it likes, then start adding coral. Even then, it's no guarantee. I had a GBTA that was all over the place. When it died, I found a much bigger RBTA that hasn't moved 6 inches from the spot I put it in. It's even still on the same rock in the temp tank that I'm running. It split, and now both now reside on the same rock, and don't seem to want to leave that rock no matter what happens in the tank...
