Aquarium Advice Regular
My betta was doing so good. Now his fins look like this. he was in a 20G with that red tail loach. I’m kinda in a panic wondering if they had an altercation or if he has fin rot. They have been separated due to general rearranging of tanks. This how he looked the other day. Honestly this is how he looked when I first bought him. If it is fin rot any recommendations on medications appreciated. .
