My jag had a bit of a tiff with one of my red belly piranhas. And now his entire bottom jaw is missing. There is just this meaty gaping hole in his face now. His entire bottom jaw is missing and a little bit of the top. I thought I was gonna have to euthanise him. But I couldn't bring myself to do it. He still had such a will to live. Continued to chase other fish away from his territory and kept all his confidence and bright colours. As days went by, he started eating again, without a jaw. With difficulty at first, but now dosnt seem to have a problem. He is eating tilpia and hake again, and even caught a cricket from the surface, out of my RBPs mouth. And my jag seems as though it has started to grow his jaw back? Is this possible?
