What is the wound?

First a big :welcome: !!! I had an octopus, think it was Ink who had the same type injuries. They did eventually heal but never regained the same color changing pigment abilities in those areas. Make sure your water parameters are ok especially the ammonia. Sometimes octopuses skin can be extremely sensative to an ammonia spike! Good luck!
