Hi G3rn.
Your new frogs will love that viv if you give them enough stuff up high to live, travel, and perch on.

Here is a little list of things I suggest for new RTFs.
1. Place the tank in a quiet room and not in direct sunlight. No special lighting is needed for your frog.
2. Cover three sides of the tank and remove any night lighting. They usually become inactive at night and shy away if night lighting is used.
3. Ensure their environmental needs are met such as temperature and humidity. 68- 70 degrees night is fine and 75-78 day temps are good.
A basic 20 to 26 watt Reveal 6500K color temp Daylight compact florescent bulb should be enough to support daytime temps and live plants in your tank. I use two on that size tank.
3. Ensure water is either chlorine free (bottled spring) or treated tap water.
4. Limit the times you enter the tank to only when changing water and adding or removing crickets.
5. Monitor humidity and temperature and mist once to twice daily.
6. Provide enough natural accents to allow for hiding, climbing, and perching above the substrate. Since your frog lives in trees, they are rarely found on the substrate and prefer to move from leaf to vine to branch to explore the tank. I use Plantation Soil or Zilla Jungle Mix and both can be found at most good pet stores. Either also works great with supporting plants. Also, have a drainage layer below the substrate. If you don't you'll be going back to add it later when you find your soil is always soaked and rotting.
7. Slowly remove covered sides over a few weeks to let them become accustomed to their surroundings.
8. Ensure the crickets provided are no longer than the width of the frogs head. Dust crickets with calcium every other feeding or at least three times a week. Check out the cricket bowl feeding method which saves on a tank full of loose crickets and helps with monitoring how your frog is eating.
9. And last but not least: Monitor the frogs activity and weight. If your frog moves around at night in the dark and soaks or sits at the water dish edge, then he/she is doing fine.

Hope this helps.
