I think I might have had a fungus too. I went to the pet store and bought fungus tablets and I took all of my plants and rocks out to clean them. I also bought a vaccum. I'm going to vaccum everything and start new. I don't want to break down the whole tank. I think I'll just let the tank run with no fish for about a month. That way I know it's safe for my next group of fish. I also bought a small tank so that I can quarintine fish before I put them in my tank. AND I bought stress coat. I really appreciate the help!!
