Centipede looking thing?

[Jackg962]

I have several centipede looking critters in my refugium. They stay underwater. They are redish and about 2 inches long. Any ideas if these are and are they good or bad? without a picture

Without a picture it's just a guess.

Agreed. Harmless detrivores.

Just a bristle work no need for alarm!

Bristleworms, peaceful and make great scavengers for getting deep into live rock, reef safe, the only issue is they can get really really big and ugley aquarium inhabitants.
