What is this?

Hello, I noticed a white, snail type creature on a frag plug. It was not there when I put it in a month ago, so I assume it crawled from somewhere else in the tank. Anyone know what it is?

Someone more knowledgeable will be along shortly but I hope it’s an okay thing cause it’s kinda cute.

I was thinking it was a shell from my sand bed, so I tried to blow it off, but it didn't move at all.

Looks like some sort of limpet to me. I'm no expert though just participating in the guessin' game!

Are those white specs on the top sand or apart of the critter? Does it have a shell? Does it move?

To me, it does not look like they are a part of it. It has shrunken and moved a little.

Looks like a limpet to me as well, with some tube worms on its shell.
