Sundial snail?

[scubasteve80]

Hey there, wondering if I have a sundial snail here. One of my biggest zoa colonies is about 30% the size it was two months ago and I heard Sundial Snails are zoa predators. This guy is tiny, but he might have some friends helping...

It does look like a sundial.

Hmm I think Collonista.

Possibly. Not sure if that's better or worse?

Does it have an operculum ? (The trap door on the foot)
This is a good pic of a sundial here

Is it small like the size of a pea or a tad larger than pea ?

Much, much better.
They breed and consume algae.
Oh, and I second Collonista as well!
