What kind of worm is this?

Found this guy. Very active at first. Constantly wiggling in the water. Pretty good swimmer. That’s a pod lower left in first pic…

You have it contained and out of aquriam, best to keep it that way

Resembles a bristle worm, kinda, but those don't swim...at least they never have in my tank. Without a clear ID and with it swimming, I'd say remove.

I’m not letting it go just wanted to identify the species. It was never in my DT, saw in another tank.

Would you say this looks similar?

Yes, but it still doesn't narrow it down much
