I recently brought home nine baby WTFs, more than originally planned, but when my fiance saw the first five the morning after we got them, she urged me to go rescue the others. The transition in their colors and dispositions, well, I didn't take too much coaxing, even if it means buying a second and even third terrarium as they grow.
Have some pretty blues in the bunch, one pale yellow, don't know the sex on any except one. And then I got a good look at this one the other day, here is the same frog in light/dark for comparison. I know he has something eyes, blue/silver? not sure what you would call the color scheme he has going on, other than eye candy. =p
