Looks like a bobbit to me.

Congrats!! You just eliminated a tank destroyer that is often hard to catch which is a Euniced worm also known as bobbit
Place in freezer then discard on garbage day

Natural pasta noodle, catch a couple more and you got an Italian meal.

Seems like there has been an uptick in the frequency of these horrors showing up.

Do they reproduce? It was on a new goni I got from an LFS that I guess I won’t be using anymore haha. Thanks everyone for the help!

Definitely not a bobbit, it’s just a largish polychaete worm. If it were a bobbit/eunicid, you would see the tentacles on its face (which wouldn’t taper like this one’s does) and be able to make out it’s jaws/teeth. It’s probably good you got it out, when they get that big they can be a threat to any small fish or inverts you may have. Also, I wouldn’t stop shopping at an LFS just because you got a hitchhiker like this, unfortunately if you want corals that are wild caught or maricultured (and even aquacultured corals can have these), it’s just the price you pay. These worms are pretty tough and so dipping corals doesn’t always get rid of them. If they become an issue, you can set traps for them, but really only the massive ones pose any threat to your livestock.

I just had chance to view this worm on a full PC screen rather than on phone and stand corrected and agree on large polychaete worm. These worms normally stay hidden in the sand and rocks, though they are occasionally seen crawling about on the walls of the aquarium. They are seen feeding on planktonic algae or other planktonic organisms until they eventually undergo a metamorphosis to the adult body form.
