Here is a down and dirty on vivarium construction. You can go from here and get as elaborate as you want.

In the bottom of the tank lay down 2" of LECA or aquarium gravel.

Cover the gravel with 3" of coco fibre. If you use LECA put a screen between the two.

Landscape this by making hills and valleys as you see fit.

Plant your live plants. You can use local varieties if you collect them from the woods where there are no pesticides or fertilizers. Small ferns and deer clover do very well.

Cover the whole ground layer with a thick variety of moss.

Add a bunch of long sticks that are at least as wide as the frogs so they can climb.

Lastly add a water bowl or something that holds water. This needs to be filtered or cleaned regularly.
