My Betta Onyx has a partially torn pectoral fin this morning. I have a 3.5 gallon tank with a filter and a 5W the temp is between 78-80°. I tested the water specs today and everything is within normal. He's swimming around happy.In fact he's even adding to his bubble nest. Should I be worried about his injury?
I've attached images, but it's hard to see his damaged fins he's so dark.
