No idea what this is. Please help.

Apologize for the bad video. I tried to edit it but didn't do a very good job. Anyway, have seen what I think is the sane thing on a frag plug. See it at night and stretches probably an inch or more. I thought it was some sort of tube worm but then saw this one tonight.

Looks like what I have, look up Medusa worms and see if they match. They're actually a type of sea cucumber.

I don't think it is a Medusa worm. Looks different. I took the frag out originally and tried to scrape it off. Thought I got it but I didn't. It retracts or something. I don't know it might be. I have no idea. Thanks for the response
