So, I've been a gecko owner for less than a month, but I actually have some experience with this...

Yay!
Lola is pretty active during the day - I'm not sure about at night because I'm not in my classroom at night. But during the day, she walks around a lot - which the kids love - and sleeps out of her hide (another treat for them).
Tony sleeps a lot during the day, but during quiet times of our day (independent reading, writing...) he comes out and chills where they can see him and he can watch them. I swear he thinks they're weird and a little creepy while Lola seems just as interested in them as they are in her.

It's cute. The longer they stare at him, the sooner he goes back under his log. The longer they stare at her, the longer she stares at them.
