Are these Pyramid Snails

Over the last week I have seen a bunch of these little white snails crawling around the tank would like to know if they are reef safe or not?? I have not seen any on my clam but I'm a little worried? Any help would be great.

I'm pretty sure. However I think there is another species that looks similar. The only way to really tell is to look at the snail's occulum (trap door). I think the pyramid snail has a pyramid shaped occulum. This is scraping at my memory so I could be wrong...

It doesn't appear to be a pyramid. To tell you have to look at the very tip of the shell. If the final whorl is perpendicular to the rest of the coils of the shell it's a pyramid.

^^Thanks for the reply; so I guess I have to catch one and turn it over and see what it looks like.
