Your fish has been having issues since August? Sadly, sometimes sick fish reach a point of no return...sorry it is just a sad fact of life. Just adding from looking at the pics, the white looks to be just the normal scale coloration. Just a guess, but from the pics of both of the fish, it sure looks like a combo of shipping stress and ammonia/nitrite poisoning...perhaps you might like to read the stickies about the nitrogen cycle that are at the top of the main pages.
