OK, so I have a Long Horn Cowfish, not exactly a puffer but maybe you guys can help. I have had him a long time, about 12 years and he has lived in about 3 different tanks. Long story short, he is having eye problems and I cant figure out what it even is. First thought was popeye, but its not from what I can tell. Woke up one day about 2 weeks ago and the inside of his eye, under the outer lens looks like its drooping over the inner lens. Almost like he has an inner eyelid, which they do not. I posted this weeks ago on 3 other boards and no a single response. I am hoping someone here has seen this before or can even guess with is going on. Parasites? Infection? Any ideas welcome, this guy is more then a fish to me, has a lot of personalty, really need some help. Thanks in advance.
