Chai Nat Help what went wrong？

　　Help what went wrong？Two weeks ago, I came to add half a bag of salt. I found a rotten mouth a week ago. I picked up potassium permanganate and wiped the wound to change about 1/5 of the water. I added another half bag of salt.The wound is almost healed, and the gills look normal. Now the fish looks like its not breathing.But there is no problem with other fish!There is foam on the water.
