“Green tree frog” is a common name shared by several frogs, so check the species first. The small American green tree frog and the larger White’s tree frog need different tank sizes and feeding. Most green tree frogs need a tall, ventilated tank, daytime warmth near 23 to 27 C, humidity of 50 to 70 percent, live insects dusted with calcium, and very little handling.
Search for a green tree frog and you will find at least two very different pets. One is a thumb-sized American native. The other is a heavy, calm frog from Australia and New Guinea. Their care sheets are not interchangeable.
This guide helps you pick the right species, then gives a shared setup and a first-month plan. For details on one species, use our American green tree frog care guide or our dumpy tree frog care guide.

Key Takeaways
- Always confirm the exact species before you buy a tank or food.
- Both common pet green tree frogs are arboreal and need tall, ventilated enclosures.
- Day temperatures of about 23 to 27 C suit the American species, while White’s tree frogs sit warmer in a vet-sourced gradient.
- Offer insects no larger than the frog’s head or the gap between its eyes.
- Handle as little as possible and wash hands afterward.

Which green tree frog do you have?
The American green tree frog (Dryophytes cinereus) is small. The Florida Museum gives 1 to 2.5 inches (about 2.5 to 6 cm). It is native to the southeastern United States, and it lives in vegetation near water.
The White’s tree frog (Litoria caerulea), sometimes sold as the Australian green tree frog, is a medium-large frog from Australia, Indonesia and New Guinea, according to the Royal Veterinary College. An exotics vet guide lists an adult size of 50 to 110 mm.
If a seller cannot name the species in Latin, ask again or choose another seller. The right size tank, temperature and meal depend on the answer.
Species comparison
The table pulls the main numbers from the sources we used. Where sources disagree, the range is shown.
| Need | American green tree frog | White’s tree frog |
|---|---|---|
| Adult size | About 3 to 6 cm | About 5 to 11 cm |
| Tank | 45 x 45 x 60 cm for 2 to 3 frogs | About 45 x 45 x 60 cm for 1 to 3 frogs |
| Day temperature | About 23 to 27 C | About 24 to 30 C or higher, sources differ |
| Humidity | 50 to 60 percent day, higher at night | 60 to 70 percent |
| Adult feeding | Every 2 to 3 days | Every other day or less |
Shared setup rules
Both frogs climb, so height matters more than floor area. Choose a ventilated tank with a secure lid and a front door if possible. Fill it with sturdy plants, branches and a hide.
Provide a shallow dish of dechlorinated water. Pick a substrate that holds moisture and is safe if swallowed. The RVC names cocoa fibre for White’s tree frogs, and one pet advice site suggests moss, bark or mulch for the American species.
Heat the tank gently, with a thermostat for any heat mat or bulb. Guard heat sources so the frog cannot touch them. A hygrometer in the middle of the tank shows whether your misting routine works.
- Tall, ventilated tank with a secure lid.
- Branches at several heights, plus a hide.
- Shallow dish of dechlorinated water.
- Thermostat-controlled heat and a hygrometer.
Temperature and humidity
An Exo Terra guide for the American species gives 23 to 27 C by day with a night drop to 18 to 21 C, and humidity of 50 to 60 percent by day rising at night. A retailer says temperatures should not exceed 27 C.
For White’s tree frogs, the RVC gives a basking spot near 30 C, a cool end near 25 C and a night minimum near 21 C, with humidity of 60 to 70 percent. An exotics vet lists a basking spot of 35 C and a daytime gradient of 24 to 29 C.
Because the sources differ, start in the middle of each range and adjust after you watch the frog.
Water and cleaning
Provide enough water for the frog to sit and soak, and treat tap water with a suitable conditioner. The vet guide for White’s tree frogs says to change the water daily. The RVC advises spot-cleaning every day and a full clean of the vivarium monthly with an amphibian-safe disinfectant.
Rinse everything well and let it dry before the frog goes back in. Keep cleaning tools for the frog tank only, and wash your hands afterward.
Noise, activity and daily routine
Both frogs are mostly nocturnal. The Savannah River Ecology Laboratory describes the American green treefrog call as a loud, nasal “reeenk”, so a male may be noisy in the evening. The RVC says White’s tree frogs are naturally nocturnal and not always very active.
Plan feeding in the evening, when the frog is awake. Check the tank in the morning for temperature, humidity, water and leftover food.
Lighting
The RVC recommends a low-output UVB lamp for White’s tree frogs, run about 12 hours a day. For the American species, guides disagree. One says UVB is not strictly required but helps calcium metabolism, and another says no special lighting is needed.
Ask an exotics vet if you are unsure. If you use UVB, replace lamps on the maker’s schedule, as lamp output fades with time.
Feeding basics
Both frogs eat live insects. Crickets, cockroaches and locusts are common choices. Feed prey no larger than the frog’s head, or the gap between its eyes for White’s tree frogs, to avoid impaction.
Gut-load insects before feeding and dust them with calcium and a vitamin and mineral supplement. Remove uneaten insects within 30 minutes, as the RVC advises.
Young frogs eat daily. Adults need less. The American species is fed every second or third day in the Exo Terra guide, and adult White’s tree frogs are fed every other day or less. Overfeeding is a common problem.
Your first-month plan
A plan helps new keepers settle. Keep notes so you can see changes in weight or behavior.
- Week 1: Run the tank without the frog. Check temperature and humidity twice a day.
- Week 2: Add the frog and leave it alone, apart from feeding and water changes.
- Week 3: Spot-clean daily and check food portions against the frog’s body shape.
- Week 4: Do a full clean of the tank and review your notes with an exotics vet if anything looks wrong.
Handling and hygiene
Handle as little as possible. The manufacturer guide notes that these frogs may leap and hurt themselves, and that their skin is sensitive to soaps and lotions. An exotics vet recommends moistened, powder-free gloves.
The CDC says amphibians are more likely than other pets to carry harmful germs such as Salmonella. Wash with soap and running water after contact. Children under 5 should not handle amphibians.
Health signs
Red or swollen eyes, wheezing, lethargy and loss of appetite are warning signs listed by a pet advice site. A vet guide also names obesity in White’s tree frogs, with cloudy eyes and a swollen body.
Do not treat these at home. Find an exotics vet through the ARAV directory. Quarantine any new frog away from others for at least 30 days, as the vet guide advises.
Common mistakes
Avoid these early errors.
- Buying a tank before confirming the species.
- Using a low, wide tank.
- Overfeeding adult frogs.
- Letting temperatures run high without a thermostat.
- Releasing a pet frog outdoors.
Buying and legal basics
Choose a captive-bred frog and ask about its feeding history. Do not collect green tree frogs from the wild. Rules on keeping amphibians vary by country and state, so check your wildlife agency.
If you are still comparing species, our pet frog guide covers more options.
Lifespan and long-term plans
The Exo Terra guide says American green tree frogs live up to about 7 years, while the RVC and exotics vet guides do not state a lifespan for White’s tree frogs. Ask a vet what to expect before you commit.
Think about the long term. If you can no longer keep a frog, ask an exotics vet or a rescue for help. Never release a pet frog into the wild, because it can spread disease and may compete with native species.
Frequently Asked Questions
Which green tree frog is best for beginners?
The RVC calls White’s tree frogs fairly hardy and suited to first-time keepers. The American species is smaller and needs a tall tank. Choose after you confirm what you can house.
Do green tree frogs need UVB?
The RVC recommends low-output UVB for White’s tree frogs. For the American species, guides disagree, so ask an exotics vet.
How often should I feed a green tree frog?
Juveniles daily. Adults every other day or less. Check body shape to avoid obesity.
What size tank do I need?
About 45 x 45 x 60 cm suits two or three American green tree frogs or one to three White’s tree frogs.
Can I handle a green tree frog?
Keep handling to a minimum, and wash hands afterward.
Can green tree frogs live together?
Some can. Check the species guide, and quarantine new frogs for 30 days.
Is a green tree frog noisy?
Males of the American species call loudly, and the call has been described as a nasal “reeenk”. White’s tree frogs are described as nocturnal and not always very active.
Bottom Line
A green tree frog is not one animal. Start by naming the species, then build a tall, humid and well-lit tank to match it.
Follow the first-month plan, take notes, and ask an exotics vet if the frog stops eating or changes shape.
