I was heading off to work tonight and went to feed my fish before I left. I was in a hurry but noticed 2 of my discuses looked ill. One is a pigeon blood about 4" that didn't eat and looked a little sunken in. The other is a red turk about 2" that was hiding in the corner when the food came out so I couldn't see him. They were eating fine yesterday so I don't know what's wrong. I can't see them now as I'm at work so I'm sitting here worried sick about them! I can't wait to get home tomorrow to check them out and first thing I'll do is a water change. Cross your fingers.
