These frogs basicly just need room to roam and explore.

Depending on how many frogs you plan on having will determine size of tank.
If you were doing 4 frogs a 15 or 20 gallon tank wold be fine for these little guys.
You will want width over height.

Basically, you would want to set up a tank with a drainage layer, screen, then the plantation soil on top.
If you design with the plantation soil to have hills, add in some basic accents such as coco huts, vines (I like Monkey ladder), a stump or other pieces of wood, then your plants, you will have created enough to have them hunt, climb, hide, and explore on.

A canopy glass top would close in the tank and keep the humidity in from misting a few times a day or having a misting system.
No need to water features since they get their drink from the moisture on leave and such by absorbing it.
I also like to use coco pods which will hold water in case they want to get wet for some reason but not be too deep for them since they are not swimmers.

Then have some good lighting that is using bulbs with 6500K color temperature.
If you room is cooler, then you may need to *** either some lighting that puts off a little heat, or a under tank heating pad on the side of the tank.

look through some of the build journals and read the care sheets for them. Have everything built, planted and the temps and humidity right before buying them. Bet way to get started and you learn alot about the tank setup before hand vise stressing them out later always trying to correct or change something.
