Then you will want to read this care sheet.
Frog Forum - Gray Tree Frog Care

When you set up the enclosure keep height in mind since they need to climb and are rarely on the bottom. Provide lots of branches, larger leaf plants, and daily water changes with dechlorinated water. Also pay attention to humidity and temp too.
When providing crickets, ensure they are no bigger than the width of the frogs head.

Yep, I just read that, thanks

I will definantally add branches and try to get a taller aquarium
