I have had my Betta for 6 months. He is happily in a 2.5 gallon that is filtered, heated, has a hood and a light. The constant temp is 80 degrees Fahrenheit. It has 2 plants and a small ornament. Recently he has been suffering fin rot. My mom got "AmQuel Plus" by Kordon and " Proper pH 7.0" by API. She didn't buy a test kit like I asked, and she didn't buy AQ either. The Betta used to eat Aqueon Tropical Flakes, but I changed to Hikari Gold pellets after I found out that you shouldn't feed Bettas tropical fish food. Can the stuff my mom bought, AmQuel and the pH regulators help my Betta with fin rot? PLEASE help I am really worried! Here is a picture. One is when I first got him(12-24-11), the second is as of now.
