Well this might suggest a nutrient problem. If you have a very large population of them then perhaps you have a build up of detritus or waste somewhere. You might want to check your water quality. Hmmmm....got crushed coral as a substrate?
Yes fish will normally eat them as a natrual food source. I know a wrasse would take care of them.
