New here! This is our first betta, he is a koi and his name is Cobalt, I was looking at him tonight and I noticed his tail fin had some differences in length. I can’t remember if it’s always been like that but I was curious what others might have to say. The photo with him more pale was when we first got him. Does it look like he’s biting his own fin???
