Yellow watchman turning white

After coming back from a 4 day trip my yellow watchman goby is turning white. Should I be concerned? What does it mean? What can I do for him?

nothing changed in the tank and i had an auto-feeder setup. sadly, the goby died. no other fish or coral have had any problems.
 
Ouch sorry for your loss. Discoloration is usually the first sign of a stressed fish. Any bullys in the tank?
