They are normal. Most rerf tanks have a bunch. If you want to be creeped out look for the YouTube video on bristle worms in sump pipe. (most likely from overfeeding)
Only be careful with clams. The can crawl underneath your clam. Had one inside my clam and killed it. Maybe my clam was ill. Since then i remove them just in case.
