Temperature

The ideal environmental temperature range for the Green tree frog is between 20 and 25°C. but the water temperature does not have to be within this particular range. Heat can be provided by using heat pads, or ceramic heat lamps. If a ceramic heat lamp or other type of heat emitter is provided it should be fitted to the outside of the enclosure to prevent the frogs coming into direct contact with it or a hot surface which can lead to burns to the animal. Thermostats must be used to control heat sources and prevent overheating of the enclosure. Temperature in the enclosure should be stabilised prior to moving frogs in. A good temperature gradient within the enclosure is essential for frogs to be able to choose their desired temperature. The temperature gradient is created by placing the heat source at one end of the enclosure so that frogs can move away from the heat source to cooler areas of the enclosure if they so choose.

Ventilation

Green tree frogs require good ventilation. It is recommended to have secure mesh lids on aquariums and tanks for them to have adequate ventilation, while preventing them from escaping. It is recommended to have a lid constructed of a metal framework with mesh attached. Frogs are extremely capable of escaping enclosures due to their ability to climb and jump and squeeze their bodies though small gaps. For this reason, care must be taken to ensure enclosures are very secure.

Humidity

Green tree frogs require a humid environment. A slight misting or spraying of the frog and enclosure should be carried out daily to keep the humidity and moisture levels adequate. It is essential to use filtered water rather than tap water when misting or spraying to prevent frogs coming in contact with chlorine and other substances found in tap water which can be potentially harmful to them.

Lighting

Green tree frogs require a UV light tube as well as a ceramic heat lamp (if more heat is required) in their enclosure. The UV light should be a specific light that is designed for reptiles and amphibians and emits UV-B, this can be purchased from a pet store. The lighting should be switched off at night and on during the day to replicate the natural light cycle. It is recommended to use electrical timers to ensure lighting is controlled appropriately to provide a natural day/night cycle. Daylight hours should be 10 – 12 hours.
