Vermited snails?

[Brad Coughlan]

Are these webs on my candy cane coral a sign of vermitid snails?

lots of things make slime, I would use a vermitid tube as confirmation of a vermitid worm.

Would you say these look like them? I am unsure if they go in groups like these or are spaced around. These also moved whenver I touched the area.
