I see that you are new to the hobby. How long has your tank been setup and what are your water parameters? My guess would be that the clownfish and anemone are not being affected my the bristle worms. I don't consider the common bristle worms bad, but some of the larger type of fire worms can cause problems with fish and corals, but they are rare. Do you have any pictures so I can see what type of worm you really have? For getting rid of them, they make bristle worm traps and certain types of wrasses eat them.
