According to HF, you need a vet to give it too you...look all that stuff up...sounds like you are lucky...I guess I got lucky with my current 5. Got them last Sept and all 5 survived and are healthy as horses. They've been through two ich breakouts and never showed any signs of infection either time. I always keep a bottle of CP on hand to treat in QT but may need to get some of the other stuff in case.
