I think my fish have Ich. I have a red snapper and a naso tang that appear to have small white spots along their entire body. The snapper seems more bothered by it as he scratches against the bottom of the substrate. I know that copper is the best treatment, but I have a lionfish. I have tried a freshwater dip with the snapper but that didn't seem to help. I don't have a quarantine tank. Does anybody have any experience using malachite green? Any other suggestions. Thank you.
