Carpet anemones are beautiful anemones. One of the brightest color anemones you can have, but they do eat fish, and probably not suitable for beginner.
I you have your heart set on one/some, you got to put the time out to search on how to keep them.
They are certainly not the easiest animals to keep. Unhappy anemone, unlike unhappy corals, can wipe out your tank.
But there are plenty of information on how to keep all the host anemones successfully these days, not like 10 years ago. Some of them are outright impossible 10 years ago.
