Not sure what this is on my zoanthids

What type of zoanthid is this? I'm trying to figure out what I have in my tank and these look very similar.

Hard to tell from photos, not sure of this specific zoa type however I saw several other types in my tank had this issue, all of which open and operate as usual. The larger white dots have more of a spiral shape to them then the small dots .

None of these are spiral at all. They are all round. I definitely don't think they're spirorbids even if they aren't a zoa. You can see the defined edges much better in person of course.
