What the heck is this thing

This is in my quarantine tank. It’s only 20 gallons and has no fish in it. I was growing algae for fun and all the sudden this centipede looking thing showed up. There’s a couple of them.

You may have to zoom in, it’s inside of the middle tube.

Agree on the bristleworm!

for future reference, if you do some research, you will find a lot of information about a type of bristleworm which is called “fireworm”. This is a type that is highly recommended to be removed from a reef tank. Especially when small it’s not always easy to tell the difference between a “normal” and a fire bristleworm. In this case it looks like you have a good guy.
