Mottled skin on wtf

[Gayl]

I have had Whites Tree Frog for over 5 years .....Never have seen this before.
I have a morph jade green Whites Tree Frog whose skin looks different to me. It now has different shades of color ranging from dark green to light jade...... He is eating, had 4 crickets yesterday....
Seems to sit in his water alot. and also looks a little thinner to me......
Any ideas.....His temps are 80 degrees, humidity 40-50%. I moved him to a hospital tank just in case....My gut tells me there is something wrong..what do you think.

thanks
Gayl

Do you have any pics?(I notice they tend to help with diagnosing)

If you looik at the care sheet on this site, you'll see that some White's do have slightly mottled skin. Has it always been the colour it is now? Or has it changed recently?
