Welcome to RC! I would agree with everything said above (BonsaiNut might as well have written a book on nems, the way he can quote them, lol). In addition, I was wondering if you were new to saltwater or just to anemones and the forum? I ask because, just as a fair warning, if your tank is less than 5 or 6 months old, you may run into some trouble as anemones can be sensitive to new tank setups, and as a result can die for apparently no reason. If it is ever seeming to fade, I would reccommend a water change, just to be safe.
