These are when I first got him/her (May 30th 2012):
And this is a recent pic:
I've been told that it's a Hyla Cinerea and then by someone else that it's a juvenile Barking Tree Frog. Anyone know for certain what this is? I like this frog a lot (so does one of my male Gray Tree Frogs who has "fallen in love" with him/her -> guess it's the green color?).
