Worm id. Possible eunice or dorvilleidae?

[Xytrax]

Hello,

I spotted couple of these guys in my newly set up tank.

They come out at night and are extremely fast and sensitive to light. Lenght is around 8cm and width 0.5cm, but if you watch the video you can see stubby (1-2cm) one running away at the end.

At first i was 100% sure they were eunice worms, but these guys only have 4 antennas instead of 5

Does anyone have clue?

Thanks!

Pretty sure it’s some type of Eunice worm

Pretty sure it’s some type of Eunice worm

Should i try removing them? They seem to roam around the tank, so i think bristle worm trap could work.

Absolutely try to remove. Best of luck

Trap or remove rock but is Eunice worm and a true problem child
A simple trap out of soda bottle baited with a piece of shrimp works well
