I have recently discovered that my betta has gone blind after stressing for so long about why he wasn't eating or swimming around as much. He's a CT and I've had him for a month and he was quite smaller than my current VT when I got him. His vision seems to have slowly gone rather than suddenly.
I don't know if this is genetic or what? He's in a five gallon with silk plants and a few caves and the water parameters are great and I've kept up with water changes and everything. I just don't understand why he wasn't blind when I got him a month ago but now he is...
To feed him I have to use a wooden skewer and move the food in front of his face. Sometimes on the first try the pellet will sink and I have to try again, but he seems to be getting a little better at finding his food.
But anyways, haha, has anyone else had a blind betta? I'm just curious.
