Here's something of an unfortunate update:
I accidentally killed the little froggies
I got a bunch of new tanks, so I decided to move everyone from the 10g to a 20g long so they'd have more space. I was so used to the anole never drinking water out of his water dish, so even though I keep it filled I've never seen it as a super-essential part of his habitat. So, when I moved everything, I forgot to put the water dish in the new tank. Apparently one night is long enough for the frogs to dry out if they don't have water to soak in. I felt terrible!
Since then, I've caught another frog who is much bigger, but he also seems lazier. The little frogs learned to hop around some during the day to catch crickets, but the big guy mostly sleeps in the corners or even buries himself down under the bark to stay moist. Don't worry, I've got an even bigger water dish that I make sure is topped off all the time. Maybe tomorrow I'll try to coax him into hopping out into the open so I can take a picture.
I'm not 100% sure he's the same species as the little guys. He's got a lot of little bumps all over him, almost like a toad, but he's definitely a tree frog since he spends a lot of time on the glass, branches and leaves and I caught him on the side of my house. I think this one may be a Gray Tree Frog instead of a Green Tree frog like the little ones. The care, from what I've read, is pretty much identical.
