Fishes mouths turning white then dieing

As long as the product is not expired, your welcome to try it. Usually, you want to use a stronger antibiotic such as kanamycin combined with a fura antibotic for the best effectiveness. As you fish loss rather quickly, I suspect you have a much more virulent strain of flex. If you have fish that are salt tolerant, increasing the salinity to .1-.3% will help too. Heres some more info on columnaris: Columnaris (Flexibacteria); Aquarium, Pond Treatment, Prevention; Fungus, Saprolegnia

Thank you!

So it's been 6 days since I started treating with binox. I am happy to report I havnt had a single fish loss since treating. I was losing 1 or 2 fish a day before. I haven't seen any signs of columnaris after day 2. Not sure if I needed to but I gave a second dose 2 days ago to be on the safe side.
