Question
We have a pair black moores in our pond and relized today that one of them has
a eye that has turned white.  Do you know what that can be?

Answer
Fish eyes, especially those of telescope goldfish (which a black moor is), can become damaged or infected.  If the eye is white and hazy, it is probably a bacterial infection but it could be fungal. Sometimes physical damage can cause the problem or rarely even eye flukes.  Most likely, the eye is infected.  If you want to treat the fish, I suggest removing it from the pond to save on the cost of medications and the stress they might cause the other fish.  Treatment might include pond salt (at 0.1% in a tank/pond of quarantine or 0.5% or less if in the main pond), MelaFix (natural antibiotic), and antibiotics (I prefer Maracyn I by Mardel which is erythromycin).  The eye may improve on its own or be resistant to improvement.  If the moor goes blind in one eye, it should still be able to function with a good eye.  If it loses vision in both eyes, it should be kept in a tank by itself, or the other fish will eat/find all the food before him/her.  Good luck!
