you will gets lots of replies on times for adding to your tank. Listen to them. I put anemonies in way to early and they have al died. First the tank wasn't cycled and up long enough, mine has been going since Jan. and i still can't keep most anemonies. I have curly-q's. but still if i put a different one in it will not flurish, and will eventually die. So take you time on the anemone, start with the rock and sand, then make sure the lighting is right, heater and filters, all that stuff first before fish or anemones.
Good Luck...
