I need to know a safe way to treat flatworms. I have tried thinning them out but they come back with a vengence. I have corals and invertebrates in the tank along with an engineering goby, yellow tang and a pigmy angel. I would like to thin them out again and add a fish or crab that would control them. I heard that a coris wrasse, manderan goby, yellow goby, chromis, or arrow crab will do this but I would like confirmation that control is possible without chemicals. What animal is best for control. I do have flatworm exit but am concerned about a very healthy tank going bad with chemical treatment. Thanks
