I would get some Melaflex! Dude I really doubt that what your seeing is hole in the head. I would rather not post picture's of my Ocellaris but when you come over I am sure some of the pitt's will still be visable. It would be a pit(s) not scratches or superficial scraps. And the stuff your using is for the wrong remedy for sure. But I have heard/read of other using this also to cure HITH or so they say. IDK? The stuff I used is a bath and it's called Hole In the Head Cure it's in a little white and yellow bottle with red writting.
I tell you what if you wan tot get rid of this guy down the road HIT ME UP! From all the medss you have administerd he should be coo,.
