After seven months of no problem, I am faced with a severe problem, there are white rings around two of my fish's eyes and I am concerned that they are going to be ill and make the rest of the fish ill too.. am i right or is that ring because of something else ? please help. Below I have posted a link of the photos of my ill fish, please pay a close attention to the eyes !
