Hi everyone! So we have this fish, now he has been like this for about a year now. His name is mark. But one I day go into my room and look at my fish and there he is with no eyes. :| I don't think my other fish pecked his eyes out, as they are not prone to that sort of thing. Odd, I know. He is doing great, but he is really thin, he eats well, and has this white stuff on him. Now that white stuff might be a parasite (I know my tank has camallanus worms and ich) but it's not contagious because none of my other fish have it. I think it's genetic. So if you guys have any ideas that would be great!! Thanks.
