I have a female ram that just got done with her second spawn. I've had her for a couple months maybe. She has lost all her blue color on the back of her body, and now its a dark color. She is staying close to the ground and not moving around much and it seems like she is breathing fast/heavy. The male seems fine. I haven't changed anything recently. Twice a week water changes. The only thing I can think of is that for the first time last week I only did one water change, but could that have really done any harm? Especially since only one fish seems to be affected? Any suggestions would be appreciated. I know EMG has a experience with rams, Have you ever had any problems like this before?
