After I first got my fish Nikoo I noticed his fins were a little dingy and I thought maybe it could be fin rot but the tips weren't black/red or anything and the damage looked like breakage. But recently I checked his tanks and his fins suddenly looked quite worse. I think it's tail biting but I want to make sure, and if it is tail biting or fin rot what should I do for my fish?
