Looks like an ocellaris to me. I don't know from personal experience, but I've heard that Haitian anemones will sometimes eat clowns. Definitely not a good choice of anemone. As Kar93 mentioned, a BTA would likely be a better choice. Although not a natural host for ocellaris (or perculas for that matter) often ocellaris will go into BTA's. And I am certain a BTA would at least be safe and not eat your clown. Anemones are an animal you definitely want to research before purchasing.
