Some sort of bristleworm?

[Starfishandseahorse]

Hiya! I was mucking about in my new refugium I set up a few weeks ago as I cycle a new tank and I saw this little guy furiously swimming around. I’ve had bristleworms in the past, but they never swam like this... anyone know if this a tiny hitchhiker of the worm variety? Thanks!

Google dorvallidae. Sometimes when knocked off the tank glass they can actually swim around like that. See if what you caught looks similar to dorvallidae.
