The best method to keep detritus worms in check is to perform regular tank maintenance. this includes regular partial water changes, vacuuming the substrate regularly, removing dead plant matter and not overfeeding. Detritus worms are a normal part of the tank ecosystem and play a large role as the "clean up crew". They will not harm fish. You can treat an overpopulation with praziquantel. Find it in the aquarium section of the local pet store. Follow label directions carefully and monitor for an ammonia spike from decaying worms. You will likely need to clean the tank (as described above) after treatment to stabilize chemistry and/or to improve water quality. Using this treatment does not mean you can skip out on regular tank maintenance.
