My Florida gar has a broken jaw on one side of his mouth towards the font of his face,you can actually see the broken bone he still can open and close his mouth. MY question is do you think the bone can heal by itself or do you need to do something else he is about 15 inches long and he got into a fight with my gator gar, they have been in the same tank a 420 gallon and this happened a few days ago the gator gar is 24 inches long. Do not really want to set up new tank for Florida gar already moved a lot of fish that the gator was messing with.
