Ok so I went to the pet store to test my water and was told that everything was good, except the ammonia was a little high. They instructed me to do a water change. My bumblebee cichlid and tank mate were fine and swimming before cleaning. Afterwards though my Bumblebee cichlid was swimming around and all of a sudden she swam down the the bottom of the tank and is laying on her side. Her tank mate is not acting differently at all. She will move occasionally, but she is also breathing hard it looks like. Could someone help me? And tell me what it could be?
