I was just looking in on my dear betta and something struck me. One of his eyes is sort of clouded over... like a cateract or something. The other one is dark and amber. He's still very active, looks healthy to me. Been eating and all.
He lives in a filtered and heated five gallon tank with plenty of plants and a little cave.
Is a cloudy eye a sign of something wrong?... or does it mean that he might have traumatized it somehow? I don't think it's age. I've only had him for about two months now.
