Just a quick update for those interested. He is doing great! So great I have tried pairing him up again and he's locked all 3 of my girls. His wounds don't look so deep anymore, the scabs actually look like the are being pushed to the top by the new skin underneath, which means they'll probably fall off soon. If and when they fall off, the wounds open up a little, I will make sure to separate him again and keep him nice and clean to prevent an infection. But for right now he is doing good and the wounds look like they are closing very well. He still hasn't eating, but I suspect it's because he's also in breeding mode so only time will tell.
