ID please

I have noticed this snail like thing in my rockwork, wondering if it is reef safe. Its like a small shell on its back and has little frilly things that come out to move. My guess is either limpet or chiton...

They look like small little limpets.

 

[phishy2]

are limpets invasive there seems to be alot of them on the same rock.

Probably not. They are likely just finding some good grazin' on that particular rock. Those look like they may be the ones that eat some sponges in addition to the other things they scrape off the rocks, so maybe that rock has some sponge growing on it that they prefer.

Cheers,
