Definitely a limpet. They are usually harmless algae eaters, but have been known to eat SPS corals too. If you are planning on ever having SPS, you may want to remove it now, while you can.
 
I'm not a huge fan of sps corals, and i don't have any, but is that all thats at risk? if they go after anything else at all i'm just gonna pull it.
 
It shouldn't go after anything else, they are good glass and rock cleaners. I have SPS in my tank, and I wouldn't remove one if I found one, just because it's usually rare that they go after corals.
 
alright , well thats a relief, i think i'm just gonna leave it then. If anything I'll just keep my eyes peeled for it doing things it shouldn't lol.
