Need help identifying these creatures

[avifilo]

Hi,

I am posting here in the forum, a video with creatures that I have not seen before.
I took a coral out of my quarantine tank today, examined it under a microscope. And I found these creatures, they are right between the end of the coral crest and the rock.
There are no bite marks on the coral tissue.
And the coral looks full of color, healthy, with full polyps extension.


Nothing drops in the dip.

Those are interesting - I would guess those are worms of some variety, but I can't tell what kind from the video. It's interesting to watch the tubes of mucus and sediment flex as the worms move around though.
