Black Moore, white arround eyes & Red eye

Question
Hi,
This morning I noticed both eyes of my black Moore peeling or white or they lost the black normal color. Tonight I got home and one eyes looks like there is red around it and inside of it. I don't know what caused it nor what it is. Pls Help I don't know what to do. The water is fine and he ate well this morning. Now If I have to put medication is it safe to add the medication in the tank while the other fish is in it. I have had him for 8 months now and I don't know what to do.
Thanks,

Hello,
Im sorry about your moore. Many goldfish can develope cancer. This may be the case but without me being able to see it it is almost impossible for me to tell you. I would take the moore out of the tank and put it in a small 5 gallon and treat it in there with medication until the "wound" begins to heal.
Hope This Helps
