Could be so many things. cyanide poison (organe failure), internal parasites, internal infection. Hard to tell without a more in deep analysis.
When a fish is eating well and still losing weight I always suspect internal parasites. Did you feed it enough?
I had a yellow tang that was fed 3 times per day at the LFS and was only skin and bone. Once I got it I put a sheet of nori each day all day long and fed it 10 times per days and only after a few weeks of this that he finaly gained weight. They can eat a lot!
