Bristle Worm?

[NarwhalLover3]

I was looking at my tank and noticed one of my condies was closed and next to it was this giant brown bristle worm thing. It crawled into a crevice in the rock and I'm not sure if I should leave it. What I saw of it was about an inch and a half. Heres a picture.

Ya sure leave it. It is part of the CUC!

Thanks. I was just worried because it is so big and my other bristle worms are pinkish red and small.
