Welcome!!!
Let's see this tank! Photos are always fun, and, after all, who doesn't like eye candy?
You'll generally find two camps on bristles. Some say they are fine and are an integral part of the cleanup crew. Others will say they are a nuisance organism and should be removed. Personally, I believe they are a great part of the cleanup crew and have never personally had any issues with them when brushing up against them or negatively impacting my ecosystem. Some people are allergic or find them and the bristles quite annoying. The greatest issue with bristle worms is that once you have them, you're really not going to get rid of them, so embrace their biological technology and the services that they will provide to your tank.
All this being said, it's difficult to know that you have, in fact, bristle worms or some other type of marine worm. Again, photos are always helpful in this case.
Head on over to the "Meet and Greet" forum and introduce yourself. Again, a photo or two of the tank, regardless of the condition that it's in, is appreciated and helps us help you better.
