Hi guys I’m new here and I need help. My betta fish has these lumps on its side and damaged tail but I dont know why. I’ve had him for a little over a year and he was fine until about may. May is when I noticed he had a small scratch like thing on his side and since then it’s just gotten worse. I dont know what it is or what to do. Can someone please help me. Here are some pics that show what it looks like
