I have one red cap oranda goldfish. Yesterday my fish was fine, but today she seems really sick. She hasn't been eating today and isn't moving just staying on the bottom. When I got back home from work she was still in the same spot on the bottom of the tank. I did an ammonia test a little while ago and the ammonia is fine. I noticed that he has a pinkish bruise on her underside, she can't seem to move or stay balanced very well. She also seems bloated as well. I got a couple of pictures of her so please help.
