Unfortunately today, our porcupine puffer got into a scrap with our vampire tang after the vampire tang instigated a fight over some food. The puffer got a scalpel to the face and his upper lip is cut fairly deep, however there hasn't been any blood and doesn't seem to be any exposed flesh and he isn't being picked on. He's also acting okay now and is eating just fine. Is there any sort of medicine I should give him with his food to speed up the healing process? Or should I just let nature take its course and keep an eye on him? Thanks!
