I'd also like to add, that you will never tame your tree frogs... They are not dogs or even rats. They will likely never enjoy being handled.
I do have a White's treefrog (dumpy), and though he isn't tame by any stretch, he is very much set to a schedule. He knows 9 pm is feeding time, and he will (like clockwork) come down to his usual spot and eat from my hand... I've had him for a long time though. My other white's is very skiddish and she wants absolutely nothing to do with humans...
As they grow up and become more comfortable in their surroundings, and become used to the sounds of your home, they will calm down.
And Carlos' advice to cover the viv on the sides is right on, this will help them to feel more secure and therefore more calm.
