I found this snail burrowing in the substrate. It generally stays in its own "territory." I have finally decided to separate it into a cup just temporarily- if people think it's reef safe, back it goes. If not, it's escargot.
If the pictures aren't clear enough, it appears checkered black and off-white/cream. I can't seem to find a proper ID for it though right now it's between cerith and pyramid, but I don't think either are correct. Thanks!

Size comparison, snail and US dime.
