Recently these things have shown up in my tank, and lots of them. I have no idea what they are. They have a little reddish-brown body which is usually in the sand or in the liverock, and they have some small reddish legs which stick out of the sand, and then these really long, thin whitish striped arms that reach out up to 4+ inches away from their body. Here is a picture of one in my tank, you can see the arms stretching out from inside the rock.
