I have seen or read about that somewhere years ago. It is a sign of a parasite i believe. I cant remember which one since i never had it but i want to say gill flukes. I will try to check it out again and get back to you. I know i heard of that. ..
Edit : found it, i was right, gill flukes. Parasite. Here is a link :

Here is a link for the treatments they recommend. I believe there are other treatments available now as well. I knowi have seen some paraite treatments over the counter that treat body and gill flukes.

Hope you can clear this up quickly. Good eye about the using one side only on the gills and paying attention to your fish. :thumb: BTW : if you feed feeder fish or it was around fish that had been with goldfish, flukes are commonly found on goldfish and related species.
