HELP, fish melting...

[downhill_biker]

So I need help guys. I just got a new blond naso last week and the top fin appears to be "melting" away and there is white fleshy looking stuff underneath. The fish also has a couple white spots on it, but not ich, much bigger. They are like chunks of calcium chloride on the side of it's body, a couple on each side.

I figure I am going to lose the fish, anyone have thoughts?
