I have 2 male mollys and 2 female mollys in a 10 gal tank. Water is fine-tested ideal. I have one dalmation male who is swimming really fast around the tank and flipping out of the water. He is under a rock thing now swimming really fast back and forth-like he is rocking from side to side. He is not eating and it looks like he can't lift his head up. He was trying to eat yesterday but could not get his head up. Today he just gave up trying to eat. He looks stressed out and it looks painful. Anyway, I can't find any information on what is wrong with him or even where to begin to look. Help me. I love all of my fish and I don't want any one of them to suffer. I want to try to save my molly!!!!!!!!!!!
