Help Identify this Critter Please

So I have noticed this orange guy in my tank this week and thought it was a sponge or something until I saw it moving almost like a snail. Can someone tell me what it is and if it's any cause for concern? I have mostly LPS, a couple of softies and a couple of SPS. Thanks

it's a limpet of some sort I believe

Thanks, there doesn't seem to be a lot of information about them out there, but sounds like it might eat some of my coral. I'm trying to find more information on "fleshy" ones like this if anyone has any. Thanks.
