Hi all, I rescued a Bala Shark that was looking super depressed at a pet shop after losing one of mine due to jumping out the tank. I noticed he has some frailed fins and a red streak going through the top fin. I also see he has a nice scar on the front of his face. He must of been through and back before I got him. He’s safe now. With two other Balas and they all get a long great. I just treated the tank with Melafix and Pimafix after a water change and adding salt. Here are a few pics. Any idea what this red streak is?
