Hey guys yesterday I noticed my clown knife seemed to be injured on two of his fins. His left fin and his top fin. Both seem to look like the same type of injury. My clown knife is 25 inches long and is with three 17 inch alligator gars. The rest of the tank mates are very peaceful, so I would imagine these alligator gars to be the only real threat and possibility that this would've happened.
Anyways I just wanted to check and see if his injury could possibly be a disease or sickness. Here are some pics, any advice would be appreciated. I did add some salt and some melafix to the tank.
