Help IDing worm / mucus webs

[Flipturn88]

These guys don't appear to be your average bristle worm, but I can't seem to pinpoint their exact species. Caught one earlier tonight, but he's not alone in the tank. Also, I noted some mucus bubbles around the tank as I'd experienced with a Oenone worm (terrifying to say the least)... not sure if it's related, but any insight would be appreciated!

Now, the mucus-slime ball oddities... they appear like a spherical spider web

Thank you! :worried:

I vote for fairly normal bristle worm, just big.
And seriously doubting that crazy ball of yarn/spider web thing has anything to do with the worm.

Those white strings your seeing might be Mesenterial Filaments.
