I tryed this food because the person at my local fish store said it was good. After two days of them eating it 7/17 fish were sick. I kept going with the food because at the time i didnt think it was the food. After about two weeks the fish were still sick. I then decided to switch foods as an expiriment. I switched to Aqueon tropical flakes. The fish are gettingtheir color back and are acting healthier. So get Aqueon tropical flakes and not this.
