Sundial snail or Collinistas snail??

[derglas]

I found some snails in my zoanthids few weeks ago. I thought perhaps that was sundial snail. Because my zoanthids polyps were going to disappear some times ago.
But after seeing some pictures of collinistas snail, i'm confused. It look like sundial snail and i can't figure out what it is.

remove and take closer pic.

You can tell sundial by Pyramid style on the opening of their door.

The sundials I've seen are flat.

I take closer picture. this is maybe still not enough to identify but they are really tiny. (under 1/20 inch)
this is best of my camera lens.. lol

Not Sundails to me.
Herbivores. Not to worry.

Grandis.
