Hi all, I've had this issue for a long while, and I'm not sure what to do. Two of my rainbow fish have had popeye in both eyes on and off for a few weeks now. I've tried treating with Maracyn II and Melafix and neither helped. I've tested the aquarium water and the water from the tap - no ammonia or nitrites or nitrates. Water changes seem to make it worse, though. The only time it started to clear up completely was when I waited on the water change (I made sure the nitrates didn't get too high of course). I have no idea what could be causing this or how to fix it. They don't fight or act any differently than the others, and always eat just as much as they did. I would love to figure out what's going on so I could get them feeling better.
