ID sacs/ eggs

[Pipefishlady]

Good morning! Can anyone ID these sac/ eggs things?

They are only on the glass near the sand area.
There are about 8 of them.
There looks to be something inside the sac/egg.
1 pic is the best macro I could get.
I do have Caribbean clingfish? That's the only fish I can think of in my tank that would have such a large sac/egg?

Looks like nassarius snail eggs although stomatella very similar .

That would make sense if I had either of thoes but I do not...the only snails I have are 2 ninja star snails....
