Snail id please

[Tim'sReef]

Hi all, I'm transferring my reef today to the new tank, and while breaking down the sump I found these snails roming around. Since I have my hands full at the moment I can't go look them up. So if anyone has an I'd that would be great. If they are good guys then they can come along to the new tank.
