What sorts of things do dumpy tree frogs need for a good cage habitat

Tank: White's tree frogs in the wild spend most of their time in trees, and need an enclosure with lots of climbing room. A minimum 25 gallon aquarium is recommended, and the arboreal type (tall rather than wide, often hexagonal) is better. A tight fitting lid is essential, as these frogs have foot pads that will let them easily scale the side of any aquarium. More than one can be kept in a tank, as long as they are of similar size (otherwise the larger ones may eat the smaller ones).

Substrate: Larger pieces of bark, large sized gravel, or soil can be used, and can be covered with sphagnum moss (which will help retain moisture for humidity). Avoid small sized gravel or bark or the frogs may accidentally ingest it. Some keepers prefer a more bare approach, simply lining the tank with paper or paper towels to facilitate cleaning (it is a bit harder to maintain the appropraite humidity this way, though).

Decoration: Provide lots of branches, large pieces of cork bark, and foliage for climbing - keeping in mind that it needs to be quite sturdy to support these stocky frogs. Live plants can be used, although they must also be sturdy and they must be free of fertilizer or pesticide residues (on the plant or in the soil). Live plants in the terrarium can be kept in small pots to make cleaining the tank easier. Placing a large piece of bark diagonally across the cage, a couple of inches from the back wall will allow the frog to hang from the back of the tank under the cover of the bark to sleep during the day. Alternately, any sort of thick plant cover or hide that allow the frog to hide during daylight hours can be used. Covering the back surface of the tank with dark paper will help the frog find a secluded and dim area to sleep during the day.
