It's too bad I didn't find this thread sooner! When I raised up my baby treefrogs I made a lot of notes. It's so great to see more people falling in love with these guys - they are such characters and I love them dearly.

Here's an album about raising mine:

One thing I might be able to help you with is sexing them. I couldn't find any documentation on how long out of the water they had to be before you could identify the males. For me, it took 2-3 months out of the water before the males started chirping.
