One of my bigger Mbuna is laying on the sand and managing to stay upright. He's breathing realy heavy. I did a water change last night. Accidently did about a 45% change. Had the water checked just a few minutes ago and everything was dead on. PH was a little low at 7.2 but im sure that will jump up in the next week or so. Last time it was one of my Johani's that went through this and he ended up dead later that day. I would hate to lose another fish. What could be the problem. All the other fish are ok except for him.
