external infection is usually isolated to the specific area it affects initially before spreading...
with the symptoms you described its something internal... obviously effecting fishes organs etc... to get an even discolouration throughout the whole fish...
not easy to give advice when you dont physically see the fish with your own eyes but IMO its an internal issue and your only point of attack is to treat for internal parasites/bacterial infection...\
at least you can get most medications... here in australia you are very limited as to whats available without knowing a vet with an interest in fish....
lets hope its something that can be cured... and its not cancer or something you cant reverse :thumbup:
