I turned the light on in my fishtank today and found 2 things: 1. The goldfish had its eyes "plucked" - simply they were missing from the sockets, and the goldfish was swimming upside down gulping for air at first, then tumbling and swimming normally for some time and swimming on belly again. At first I thought maybe its dying, but now I think its simply disoriented and the missing eyes are to blame. The reason for missing eyes could be #2: http://carboninside.com/fish/IMG_0063.JPG http://carboninside.com/fish/IMG_0057.JPG 2. The other species of fish in the tank seem to have some addition. About a dozen or so new small fishies swimming with them. Perhaps the species attacked the goldfish in order to protect their spawn from being eaten by goldfish http://carboninside.com/fish/IMG_0060.JPG Is there any known behavior like this out in the wild? If not what could've caused the goldfish to lose both of its eyes?
