I'm just wondering how agile young whites tree frogs are. I've had 2 whites for approx 3 months. Both were same size when I got them and now one is much bigger than the other. The smaller one doesn't seem to be able to jump very far. I have also noticed that both seem to fall on their back quite a bit (although they can correct their position). The smaller one doesn't seem to be able to hunt the insects as well as the bigger one and doesn't seem as interested in worms as the moment. Any advice/tips welcome.
Mine used to be able to leap from the very back of their 45cm viv to the very front door, where they would then 'do a Garfield', sliding down the door. So in my experience they are VERY agile usually. I would be a bit concerned about their hips.
Oh and just to check, you are supplementing their food with calcium aren't you? It's extremely important, especially for juveniles.
