A friend of mine treated her tank with peroxide (it was second time she did it so I assume she has her dose right at 1/2 bottle for 75 gallons?). Many of her fish died, but her jewel has a swollen Gill on the left side. It almost looks like someone put a small balloon in there. She says it has gotten bigger but otherwise fish seems fine/is eating/swimming/defending itself.
Any tips or ways to treat it? I've never seen anything like it so have no advice for her. This happened a few weeks ago and we thought it would be a gonner but since the poor thing is still hanging on I was wondering if there wasn't something she can do.
