Had the exact same worms as your. I don’t see them any more . Not sure if they died off or what.

Google Dorvilleidae

Yup, that's it. Ive had bristle worms in other tanks but never saw them this small. dorvilleaidae worm explains it. I observed it munching on algea so I wasn't concerned, just curious what it was. Thanks
