Hi! I am new here. Pleased to see a great community such as this. Here is my issue. I am not sure what is going on in my tank. Is it a bully or a disease but I have had two fish now afflicted with this problem. The first is dead and I hope the other doesn't. The left eye, only the left, begins first by turning whitish and then begins to swell. The one that died began to swim sideways with the bloated eye towards the top of the tank almost as if it were more buoyant than he could handle. Strange. I can't seem to find any good info about what to do. Any ideas???
