Thanks! I am going to go by the store tomorrow to pick up some more crickets and mealworms. A seperate feeding enclosure is a good idea! I really hate crickets, so I'll have to find a way to feed them that doesn't involve me touching the crickets.
I don't have room for a bigger enclosure at the moment, but I am saving up for one that is about the same size, just turned sideways so it's taller than it is wide. I wanted to get one to begin with, but my parents bought a bunch of stuff for me as a present and I felt bad selling it to buy a different one because they were really proud of themselves. (: Haha.
Also thanks for the handling tips! I was told at the reptile store that white's are more handle-able than other tree frogs, and they don't seem to mind me lightly touching them on their backs, so I will just stick to that unless I have to move them.
Thanks for the names as well, I will look at those!
