Fuzzy little ball on live rock

[Idaho Mojo]

Cant tell what this little guy is.. kinda looks fuzzy and has some bristles sticking out of the end. I'm pretty sure it moves unless I havent noticed it before or it just recently attached to that spot.

Awesome! Thank you!

The vermatid snails were prominent in the tank before I bought it and rebooted. From what I can tell, they're just empty shells with coraline growing on them. They were EVERYWHERE on the rock work when the last guy had it running before.
