Worm in my rocks

[LittleFishiez]

Hello, I found this little guy underneath a rock of mine while cleaning the tank. Any ideas as to what it is?

Bristle worm.
Part of the 'hidden CUC'

what ever you do don't touch it with bare hands , the bristles can get lodged in your skin
and cause a very uncomfortable irritation ,

It`s just a bristle worm. Came in on your LR. They are great janitors and OK for the tank. You can control their numbers by not over feeding.
