Good news! The red light lamp hooked to the thermostat works splendidly! We held around 81 degrees all night.

It dries out the humidity a little faster, but that's not that big a deal. It just means I'll have to mist down the enclosures a little more. I also got the kids some little plant things that they're enjoying sitting under. Hoorah, happy frogs!
Two things I've also learned:
A) Georgie kind of sucks at catching her own food, lol. She's very lazy. She seems to think that if she sits there and opens her mouth in the direction of the cricket that it's just going to hop right on in there. She's much better with the tong feeding, and she still doesn't seem to mind if I need to handle her a little. Hoorah for mellow frog!
B) Mason is a little machine! He goes after crickets like it's nobodies business! On the flipside, he
hates being handled. I needed to move him out of his water dish so I could clean it, and he did that thing like my lizards used to do when they were first getting used to being held: "I'm going to open my mouth in anticipation of one your digits accidentally slipping in there, after which I fully intend on biting you!" He also peed on me, lol. He's definitely going to be my "look, but don't touch unless absolutely necessary" frog.
