Ok, so I got home from school and turned my tank light on, and one of the eyes of my figure 8 puffer is all huge, swollen and red!! it looks like his eye has a huge red bubble on it, and the bubble has like, a swirl like a snails shell on it... its really bizarre and I see nothing like this in the disease datebase... Im thinking he scraped it on a rock or something when he got startled (everyone once in a while he bugs out when I shut the light off or turn it on etc). Any ideas on what this is and what I can do?
