It just looks like it would being freshly introduced into a new tank. I'd guess it would be fine. If I was to guess, it looks like a BTA, but from your pics, hard to make a positive ID. If it lives in a brand new tank, it probably is a BTA, they're pretty hard to kill, although, people still manage to kill them.
It may or may not move on it's own. Just let it be. Your light looks a bit strong, so it may wander until it acclimates. I've had mine wander until they find the "sweet spot" of flow and light they like. Mine also have lost bubble tips in different systems. When mine have bubble tips, they wander. When they have no bubble tips, they usually stay put.
Your clowns may or may not host it. I'd guess they will, but you never know. I have a pair of onyx, host all day long in a sebae. Another pair of tomato's host in a couple BTA's. A pair of Occelaris(sp?) clowns refuse all anemones, and host in a toadstool leather and xenia. None of them are in the same tank. You never know what they'll do.
