I am new to the hobby and have my 2 koi betta. I only bought my second one a couple of days ago and I thought the coloration on his mouth was his pattern. When I checked in again today, it looks like its spreading and he is not esting as much. I think it might be cotton mouth? Can someone please advise. I've attached pictures here.
