Bristleworm? Put it back?

Sorry the picture isn't the greatest but it's pretty tiny. That's 6x zoom on my phone and he's still small.

Slightly better picture...maybe...

When in doubt take it out. Doesn't look like a normal bristle worm, but it's hard to tell

Polychaete Dorvilleidae.

Thanks. He's still in the cup while I debate whether to drop him back in. He was in my invert QT tank so I've also debated moving him to the display.
