questionable inhabitant?

[KENM]

Hello all,
Let me start off by stating that I have no idea where this particular creature came from. I've added nothing to my tank for at least a month, and what I did add couldn't have harbored anything of this size. I did, however, purchase a small piece of rock with 5 yellow polyps on it. I only mention this because after it was placed in the tank I noticed something else sticking out of the rock which turned out to be some kind of serpent star fish (really cool). Anyway, thanks in advance for any relative info. The pic appears in my member gallery under, believe it or not, questionable inhabitant.

To me, it looks like a stomatella snail. If I'm right, it's reef safe.

You can learn more about them here http://www.reefkeeping.com/issues/2004-05/rs/index.php

Best of luck,

Thank you very much for the info, I am glad that I don't have to remove it. I've definitely gotten lucky with hitchhikers so far but that can change in a moment. I have another creature, a flat, white thing that I see occasionally on the glass but have not been able to get a good pic of for I.D. purposes. When I do, hopefully one of you fine folks will recognize the little fella and be able to tell me what I've got. Anyways, Thanks again for the info,
Ken

For the other creature, here is a good site to try to identify it. http://melevsreef.com/id/

Thanks for the link, right there on the first page for that group. The only info says it's a benign flatworm, don't know if thats the name or a description, but thanks again for the help.
