I did this to get cipro for a lot cheaper than fishflox cost. Explained that I use it to treat infections in carpet anemones. She wasn't hesitant at all, I did spend half an hour talking to her about it because she was interested.I know it sounds crazy but call Your local Vet and explain to them what you are going to use it for. You will find one who will sell it to you. That’s how I used to get mine back in the day.
