About a month ago my lonely survior in my bass tank got his eye poked out by the crawdad. So I was like nice I got a one eye goldfish. Well some kind of fungus took over and now his other eye is gone and he cannot open his mouth. He won't die either he hasn't eaten since October. Should I just wait till he dies or let him live? Will he give my 5 largemouths the disese?

Sorry, I don't know what I saw that made me assume you were planning on feeding him to the bass.
