It looks like it could be a Collonista amakusaensis.

It is a Collonista amakusaensis, which is quite a mouthful for such a tiny guy. It is about the size of a BB, and is hiding in the shade of an Astrea above. These tend to come in as hitchhikers, and breed quite easily. If you look at your tank late at night, you'll typically see lots of them once you know what you are looking for. They never get any larger, and seem to assist in eating some algae. In the next image, with some other inverts to get a sense of scale. Reef Safe.

There are "bad" snails. I was going to say those look like collonista snails as well though, which are not bad.

Yes, there are bad snails that can exist in your reef. For example, Sundial snails are zoanthid predators and Pyramidellid snails are parasitic to clams. Yikes!

Not to mention certain whelks...
