My molly is not eating. I can see she is relaxed and she has also been separated from the other fish to reduce stress. Her belly is sorta squarish. Does this mean she is giving birth? Is she going to die? I don't know what to do. If it helps, I did a water change a few days ago. This about the same time she began to stop eating and her belly became more square like and big. Thank you, any response would be helpful.
