Cage: Golden tree frogs belong to a group of tree frogs that contains some species that literally glide from tree to tree in the wild. Although golden tree frogs can’t glide, they can jump long distances and need room to do so in captivity. A standard 20 gallon high aquarium that measures 24 inches long by 12 inches wide by 16 inches high (61 cm by 30 cm by 40 cm) is large enough for a trio of golden tree frogs, although more room is recommended. A tight-fitting screen cover should be provided otherwise the frogs will escape. Attaching an aquarium background or black poster board to three sides of the aquarium will help the frogs feel secure and make the cage more attractive.
