Today I notice that one of the fish's eyes was 1.5 times bigger than the other eye and hazy. I tried to look up some some information to find out what it was. Unfortunately there were no posts that seem to be exactly what my fish has acquired. The only thing that has been added to my tank in the last two months was 5 snails which went in on last Saturday. I will try and take a picture and post it tomorrow, but in the mean time I would appreciate any information that you could impart upon me about opaque (only slightly) swollen eyes.
