my water recently went bad and was all cloudy and had amonia in it. it's okay now but my pictus cats look real sick. They swim around with their moths open and the edges of their mouths are all red and look like they're bleeding. Also on the tops of their heads they look like they are bleeding under their skin or something all these red patches are showing through. I havent seen them eating although they are still pretty active...yesterday one of them was just swimming round and round near the surface of the tank but today he's back at the botttom again. I have added aquarium salt to my tank as i know that these fish are hard to treat with medicine what can i do and what's wrong with them?
