Hitchhikers on frags?

[NYCxJay]

Hey! Just got a couple of Frags in, and found these odd white spots/swirls on them. I already removed a Vermetid snail, and something else that was kind of flatworm looking. Any ID on these?

Spirobid worms would be my guess.

I agree with @ISpeakForTheSeas it looks like Spirorbid Worms

Thanks. Looks like they are both good and bad from what I researched. I still scraped all of them off (I think), before they went into the watch tank. Thanks again!!
