From the time I have gotten my betta, Asura, until now, the poor boy has been getting more bouts of what I BELIEVE is fin rot than should probably be healthy for what could be considered healthy for him, and just today he has another round of it even though his last bout of the fin rot was three days ago. Is it possible he could be tailbiting instead? I wonder this simply because so far it's only been one fin at a time being damaged, rather than multiple at a time. I have no pictures as he doesn't stay still long enough to get a good shot of the fins.
