Bobbit worm or no?

Pulled these worms out of my filter during my tanks water change this evening. They have clear antenna so that confirms they aren't regular bristle worms. Any ideas??

how large are they

How many tentacles do they have on the head? I’m counting four in that first pic, which would indicate that it may be a Dorvilleid worm (which should be harmless).

The longest was around 3 inches.

There are 4 antenna for sure. Images of the Dorvilleid worm actually look very similar to what I have in my tank. These might be it man. Thank you I appreciate you!!

Looks like either a eunicis or nereid worm. Neither are desired and should be trapped and removed. The easiest trap is a 1 or 2 litre bottle as pictured baited with shrimp

Heard. Thank you. I believe I eradicated the population of them. I think they had just started growing in my filter media and I cleared them out. Hopefully that will be the end of it
