Swimming worm..possible ID?

I just found a millipede-like worm, about 1/2" long, swimming in the water column. It wasn't a fantastic swimmer, but it was jetting around somewhat frantically. I scooped it out with a paper cup. Before I caught it in the water column, I noticed it sort of hanging out near some cyano. I'm not sure if it was eating it.

It is slightly orangish, and gets darker towards the head. It has a head that looks kind of millipede-like. Its body is sided with numerous small swimming legs.

When it remains still enough, its internals are somewhat visible through its slightly transparent body.

Any ideas?

Safe to re-release?

Sounds like an Oenone to me. Not sure if they swim but that's what came to mind from your description. IMO bristle worms dont look like millipedes, but these do.

"What we usualy mistake as another worm species can very well be a modified version of a bottom dwelling worm specialized to swim in the water for reproduction."

Crazy....
