Bristle worm or something more evil?

It looks like one but I am unable to confirm 100%

Yup, brisstle worm. Beneficial as long as they don't get out of control. You almost certainly have more already in your system.

Bristleworm.
While many regard this a member of clean up crew as they eat uneaten food and detritus, they can get large and increase in numbers. I dont desire them in my tanks and its up to given person to keep or discard.

Thank you all. Yes I have a few of them nothing larger than pictured. I will keep an eye on them for now
