:'(I don't know what is wrong with my fish. One of his eyes has a redish orange spot in it, and it looks like a bubble on his eye. Also it seem to me there is a haze look in the eye too. I always do frequent water changes, like every 2 to3 days due to the high amonia, and the water looks very cloudy when I don't.
I also lost my tubba, she jumped out of my tank. My neice bought me 4 little goldfish, to ease my pain from the lost. But I dont think that was a good idea, my big boy keeps chasing them around the tank. It has been a week, and he looks at them like they are his meal. Can anyone help me with my situations, also I dont think my bigboy can see out of the eye.

Did you isolate the fishes before they were introduced to your tank? did the spot in his eye appear before or after the fish were introduced?
