I just posted a thread concerning weird cloudy spots in one of my betta's eyes, and ironically I stopped by Petsmart today and saw a blind betta :(. I felt really bad for the betta, and bought him. I don't think he's completely blind, because he'll swim away if my hand suddenly appears on the glass, but if he swims *super* slowly, and he won't notice my hand if I put it up to the glass slowly. I'm keeping him in a smaller tank temporarily, just to so that's it's easier for him to move around.
I'm also concerned about how to feed him, because he doesn't seem to notice the food.
Also I would love some name suggestions :) I was thinking of Tiresias, the blind prophet from Greek mythology.
Here are some pics! I think he's a spade tail..
(I'm almost positive he's a he, because he has no eggspot and his anal fin is quite big)
