I thought this neon died along with a tailess one we had. I just found him 2 weeks after I thought he was dead. He's missing half his dang head but lives on just fine lol. Ol' One Eyed Willy!

A buddy of mine had one fish eat out the eyes of all thee fish in the tank in one night. He came home and 3 of the 4 fish in his tank had pits in their heads where their eyes were. So creepy. He dosent believe me for some reason but I believe the one fish with eyes attacked the others. Its the only reasonable answer.

only problem with this is, if there is any undue stress or a breakout of any bad bacteria in the tank, this fish's immune system will be less able to fight off the disease/bacteria

funny how some fish are capable of bouncing back

hahaha. tat happened to me as well!
