Scales can heal, but whether it's scarred or not I can't tell through the pictures. I once took a jack dempsey that was shredded to near nothing, his fins were almost all gone and his scales looked like minced meat. He got it bad. A customer brought him in. I healed him up and his scales did come back without scarring, so I guess only time will tell. As mentioned, sometimes the scales come back without the underlying pigment of that area, so the pattern may get broken, but that's just pigment. Nothing to worry about there.
