Yeah, I've actually heard that before plenty of times on this site, but nowhere else seems to mention it.
I guess what I'm wondering is how do you know if yours aren't really green deep down, but always just choosing to be brown? How can you tell what your frog's real natural color is so that you can determine whether or not they're healthy? So many sites say that if they display a bright green, that they're in great shape, but if yours are naturally brown, how can you use that advice to your advantage?
