Long story short a raccoon was able to make his way to the pond and got a hold on 2 of my smaller koi. He also ripped my 13 inch kois mouth open. There's no blood but the koi's sucker lips is ripped pretty bad. I cant get any pics now but the koi seems to be doing just fine. Will the mouth grow back again? because my main concern is that the koi wont be able to eat
