Round two with that worm guy.

I'm back with more videos of that worm. I've captured it this time! Worm1 was way bigger so 99% sure the are different worms, not sure did they are different species. Sorry about the world's shakiest camera!!
@ISpeakForTheSeas what do you think? I'm pretty sure they are the same type from their swim, but I am lost. About the tentacles, I don't know if I can see any

Okay, I'm 99.99% it's a Dorvilleidae and I don't need a tank exorcism @ISpeakForTheSeas knew it from the start!
