Worm ID/Verification

[renegaderon]

First time poster, so I hope I got this right..
I noticed worms in my QT despite my efforts to dip (however this is my first attempt at keeping coral). I’ve done some research, and I believe they’re Dorvilleidae. Is that correct or are they something else? Is this something I should be crazy concerned over?
I do plan on dipping again. Any other advice?

I believe they are, yes (just going off memory - not at my desktop).
