thank you guys, I really appreciate all the great info
so temp is now steady at 75 highest.
while thawing mysis and enriching brine, I dropped some NLS pellets in and he went for them ! not just went for them, but he was hunting them lol and begging for more ! the fish has turned 180 degrees around ! he is either just used to the tank now, or the temp drop did it, or whatever sickness he has is passed now ... who knows, Im just happy he is eating better now.
Stunreefer hit it right on the head, he then started eating chopped up mysis and frozen brine too, Red nori he seems to love as well.
the scar or the opening is still there, but looking more closely, it doesnt seem to be an infection or anything right now ... perhaps just a scrape from catching it. I am being careful doing alot of water changes in his tank as much as I can and cleaning detritus, to avoid secondary infections. Im gonna hold back from medicating for now. dont want to damage anything else.
wish me luck

Im gonna wait at least a couple of months more for him to heal fully and gain more weight. and then introduce to my reef.
really appreciate everyone here and everyone who PMed me Ideas and helped, this sure is a great community to be part of
