Are these feather duster worms?

Hi everyone!
Soooo I found these under my Candycane coral frag. No where else in the tank and Ive had this frag for 3 mos. There are no fans and there's at least 6 of them. Does not seem to affect the coral.
You guys are awesome and I appreciate your help!

Vermetid. Kill them, they release a mucus net that annoys coral. Break off at the base and cover with super glue. Bumblebee snails are said to help. Mine didn’t.
Also looks like some bubble algae in there.

Thank you! My first official pest. Lol.
I'll try to break them off and seal them in.
Gross.
