Okay I'm dumb :) American Green Tree Frog question...

Thanks for the info! I'm pretty sure she's always brown though, because I peek in on them in the middle of the night sometimes. But it makes sense that they would change color to green when it's dark.

hmmmm...mine is brown most of the time too.

They are also shades of olive green, which can look like brown in certain light. They vary in color just like gray tree frogs have green backs instead of gray.
