Kanamycin is an antibiotic that treats both gram positive and gram negative bacteria. To treat the septicemia, you'll need to add the contents of the capsule to the fishes food. Empty the contents of the capsule into a small amount of water. Add flake food until the water is absorbed. Spread the food on plastic until it dries and feed it to the fish. I have seen this med sold under the brand name "K
-Mycin" and you should be able to get it at your LFS
. If you can't find it, I would try some tetracycline. If you can't get that, go with a sulfonamide based treatment. Your LFS
should be able to supply one of these. You need to treat them quickly though as this condition moves fast and is only susceptible to treatment in the early stages.
