My snakehead Channa gachua is sick. he has on one side a hole that Is black and on the other side a bump that looks like a tumor. I once treated him for bacterial infection for two weeks but that didn’t seem to do anything. He is currently in an aquarium of 300 litres with a few bichirs and another Channa gachua who all seem to be fine. He eats well and doesn’t seem to have pain. Bud lately he is floating near the surface he can go back down but he stays there for most of the day before he lay on the ground like the other snakehead. I have tested the water for ammonia and that is near zero. The fish has had this for almost 3/4 year but it seems is had gotten worse . Can somebody tell me what it is and or what I have to do.
