Carpet is the clowns natural habitat. But, due to the painful sting of the carpet anemone, and it's finicky nature in aquaria, I would recommend the Bubble Tip anemone. I have one and love it! With all anemones, you can't guarantee the clowns will live in the anemone but the Carpet may or may not have a higher chance than the BTA to become a clownfish home (also, if you have other fish in the tank that will increase your chances of having the clowns living in the anemone).
