One of my ranchu's has a bacterial infection on one side of his gill. I have treated the tank with tetra tonic (it turned the whole tank green for a few days) and ive also placed some tonic salt in the water. The infection seems to be growing by 1mm a day. its not affecting the other fish in anyway i can see, all of them are still eating and swimming around very merrily, please help!
