=[ this is heartbreaking, I couldn't see myself dealing with as well as you are, hope your fish pulls through, he is a pretty oscar, I think someone recommended it already but it couldn't hurt to keep the treatment going till he is okay, will atleast provide some defense, in my opinion i'd keep going with the epsom salt, since finding out about the stuff I have used it in my quarantines, though before coming here I never knew just how beneficial it was to use it, just got the habit from my brother. I have no idea what is wrong with the little fella but I wish you luck in helping him recover, I can't recommend meds as I don't really use them and in all honesty like i said I have no idea =[
