If you didn't buy this anemone, I'd suggest you don't buy a carpet anemone. There are too many problems you will encounter with all 3 (+1) of the species. They are all sticky, they kill other fishes and inverts, and they kill some clowns, they grow large fast, they need deep sand ... the list goes on.
I'm not passing judgment but I'll go out on a limb here and tell you your first anemone is going to die soon after you buy it. I don't know of many if any people who have had luck with a first host anemone. You are better off with a clonal BTA. No one says you have to keep it if it grows well in your tank and you have success, but it's a better starter anemone and will give you much more satisfaction than the carpet that either dies fast, kills its tank mates, or both.
