Last weekend, I noticed a white spot on the eye of the hi asagi - when I catch him from the top looking down so the eye is in profile, there appears to be a whitish film over the eye. He seems to be either blind or close to it on that side.

I googled koi and cataracts and apparently it is not as uncommon a situation as one would think. What I am wondering is what are the chances this guy will have cataracts on the other eye? I would hate for him to be totally blind.
