My VT Betta seems to be going blind. His eyes are opaque. He lives in a 10 gal tank that also has Cherry Shrimp in it. It gets 20% water changes twice a week. Temp is 78, Am 0, Ni 0, Na 5-10. Cherry shrimp are all prospering so I know the water quality is fine. No other problems except I have to drop his food in right next to him. He gobbles 7 pellets up within a minute twice a day (I know he is a pig). I have had him 8 months or there about. He was being put into his bowl out of the shipping bag at the LFS when I saved him from that fate, so he isn't that old.
Can fish just go blind?
