Hi everyone.
So I was just wondering if anyone has had any experience with anything like this. I was doing a water change in our large koi tank and was finishing up when I noticed one of our guys had passed. I'm not sure exactly when it happened. He was swimming around yesterday and I didn't notice anything particularly off about him. Today I saw him lifeless at the bottom of our tank with one of his eyes bulging out about a 1/2-3/4 inches from his face, almost as if it were on a stalk. It seemed like some of the blood vessels around his eye had ruptured. His other eye was perfectly fine. I've looked up images of pop eye disease in koi, but they don't seem to quite match what I saw. Whatever happened, I think it was pretty abrupt. Does anyone have any idea what could've happened to him, and should I be worried about the others? If it helps, the tank itself is about 580 gallons and is decorated with river rocks and a couple bubblers and he lived with three other koi. I didn't see any obvious signs of ich. Unfortunately, I don't have any pictures of him as the whole thing was just too upsetting.
