Hi! I've had my betta for about six months. When I got him he was a tiny little dude, and hadn't even fully developed his fins, so I don't think he's that old yet. He is in a 6 gallon tank, kept at ~76 degrees F and water changed regularly. It is planted. He seems very healthy. He is a voracious eater and a lively swimmer. But he has rough looking scabby/scarred bits on his face. They are not white or puffy looking, it just looks kind of like someone burned him and it healed over. It seems like this has gradually worsened over time. He also has shiny patches on his gils/face but from thread browsing that seems like a normal part of betta aging? Any idea what it would be and if I can fix it? Thanks!
