Difficulty: Moderately Easy
Step1
Set up a glass or hard plastic aquarium that has about a 10 gallon volume. Try find an aquarium with as much height as possible so the tree frog can jump around. Place some mesh screen over the top of the aquarium to cover it. Inside, place twigs, leaves, rock and a dish with water in a way that best replicates the tree frog's native environment (which is usually wherever you found the frog).
Step2
Place a 15 watt nocturnal lamp above the enclosure and point it at one of the larger rocks in the enclosure. If you notice that your tree frog is staying away from the heated rock or the path of the light then turn off the heating lamp for a while.
Step3
Feed the tree frog insects such as flies or crickets, which are a favorite choice with tree frog caretakers. Once a week, coat the food with calcium and vitamin gel to get the frog a little more of the nutrients it requires.
Step4
Spray the frog once a day with pure (dechlorinated) water. It's best to do the misting in the morning. A few pumps on a small water sprayer (as used by hairdressers) is good enough.
Step5
Clean the tree frog's enclosure once a week by taking the frog out and carefully placing it in a temporary enclosure like a clean lidded plastic tub with ventilation holes cut in the top. Take everything out of the enclosure and scrub all items with hot water but be careful not to get soap onto anything. Once a month, clean the tank itself.
