Eyes popping out some and a white glaze over parts of their bodys and after a while it just wouldn't go away. I did weekly water changes any only fed them 1 time a day. we do have Iron in our water but I used a water treatment every time I did a water change. I just don't think that the fish are as healthy overall anymore. When I was a kid if they got something wrong with them and they rarely did you could cure it almost right away so who knows?
Its wrong on such a fundamental level that I worry that your other methods may be off too. Don't be afraid to ask questions or to admit that there is something that you don't know. That's what learning is all about.
