A raccoon attacked my fish. He got one 2lb goldfish and took a huge chunk out of the back of my huge albino catfish. I quarantined my catfish (ghost) and have been maintaining a salt content of about 500-700 ppm and adding melafix every couple of days to make sure it stays sterile. My question is will it heal? the dead skin has fallen off, the wound is clean but will a layer form over the muscle tissue to protect it from bacteria?
