Pulled This off of my Setosa

[KJAG]

Can somebody ID what's going on here? Came home and this squirming creature(s) was on my Setosa. I'm not good with pest ID. Anybody? Will try to attach a short vid since the pics are low quality. Thanks.

Spaghetti worm.

Harmless alone, but once they colonize they can become a nuisance to nearby corals.

Ya...population should be self-limited by food source, so as always be mindful about feedings, flow and filtration. ;)

Thanks guys. I've seen a few in the sand bed but never realized there was a gnarly worm anchored beneath. What's the eradication method? Baste them out of the sand?
