Hi and Welcome!
Red Eyed Leaf/ Frog - Agalychnis callidryas basics:
They need to have a dark home at night, so night lighting is usually something you need not have. They tend to hide and become less active in many keepers homes. This may not be the case for yours but is more often the case than not.
These frogs like to stay off the substrate so having plenty up high and enough in the tank to allow them to move from the top down to the water would be beneficial to the frogs needs.
Live plants such as Snake Plant, Pothos, Bromeliads, and air plants with great when used with branches, vines and a background to slide the Broms and Air Plants into.
You will find the frogs sleeping on the snake plant often.
Daily water changes with declorinated water and misting twice daily will be good for both the frogs and live plants. Humidity between 60 and 70 percent is god for these frogs also.
Temps should be around 68 - 70 degrees at night and 75-78 during the day.
I dust crickets 2 times a week for my adult RTFs and feed every other day. They are not aggressive eaters and will not usually gorge themselves but eat what they need and move on. Juvi frogs should be provided feed daily and have crickets that are not longer then the width between the frogs eyes.
Read the care sheets, ask plenty of questions, and check out some of the members photo albums for build ideas. Some of the prior months enclosure of the month entries also ahve some get pics for getting ideas.
Have fun
Don
