ID, hair like tendrils…

[DW66]

Was checking out my tank with a flashlight after lights out and came across this clump of hair like tentacles (tendrils?) emanating from the sand.

Can anyone id it from this video?

Do you have photos? Video isn’t working on my end

I am unable to see the image in its entirety, but a guess might be Spaghetti Worms, and pretty cool.

That looks like a Spionid Worm to me:

Though it also seems to match "Spaghetti Worm" images, I think I have read that this is a common misidentification, but I'm not sure on exactly which species the common name "Spaghetti Worm" applies, as Spionids are reminiscent of spaghetti for sure.
