porkypine puffer white as a ghost

[excalibur]

My puffer is almost all white, I can still see the spots but all the brownish color is gone. Any idead why this could be, He has been like this for about 2 weeks.

Does he still look like now?
It could be a number of factors.
What are your tank parameters?
Has he been eating?

are you sure your not just looking at him when the lights are off. Im sure your not but when the lights are off they will get pale.
