Swirl trail on glass

[Reefnski]

Hi all, I have a tank that suddenly has this swirl trail on the back glass. Does anyone know what this is? It showed up this morning. The only thing in the tank is a lawnmower blenny, snails, hermits, a couple zoas, and oodles of copepods.

Excellent. This will save me a trip to my LFS. I have another tank that has openings in its clean up crew.

Those look like Cerith snail eggs to me.
