My Koi have come down with a bad case of fish lice. Most research points to Dimilin as a cure but it seems to have been removed from the market. What else can I use to treat it that is readily available at most fish stores?
Just buy dimmilin online. I know a koi shop in my area still carries it and they ship. Dont use Potassium Permanganate its the nuclear option for fish wasting diseases that dont respond to regular meds.
