White's Tree Frog

Overview

White's tree frogs, also called dumpy tree frogs, are among the most popular pet frogs. They're hardy and calm, with a "smiling" face ¹². Adults reach about 2 to 4.5 inches, and females are bigger than males ²³. The Smithsonian's National Zoo puts the average lifespan at about 16 years, with one frog reaching 21 in human care. LafeberVet lists 20+ years ²³. The species is bred in large numbers, though wild-caught frogs from Indonesia still turn up in the trade ². Ask for captive-bred animals.

Natural history

White's tree frogs come from Australia and southern New Guinea ³. They live in trees rather than in water, drinking from rain caught in leaves and crevices ³. In dry seasons they shelter in tree hollows or coat themselves in a moisture-saving secretion ³. They're adaptable enough to turn up in bathrooms, water tanks and on verandas ³. Colors range from light blue to emerald green or gray, and they can change shade somewhat ³.

Enclosure

• Size. Tree of Life recommends at least a 20-gallon tall terrarium for one frog, and an 18 × 18 × 24-inch front-opener or larger for pairs and groups ¹. LafeberVet says one to four frogs can do well in a 20-gallon tank ².
• Go vertical. These are climbers. Add sturdy branches, cork bark and plants, with perches and hides at several heights ¹. A limb at least as thick as the frog's body makes a good perch ².
• Secure lid. They climb glass and escape easily ¹.
• Water dish. Shallow, easy to reach and changed daily ¹.

Temperature & lighting

Use low-wattage heat lamps or ceramic heat emitters, never hot rocks, which can burn ¹. Check temperatures at several heights with digital thermometers ¹. UVB is recommended though not strictly required; low-output UVB or full-spectrum LEDs work well in planted setups. Run lights on a 12-hour timer ¹².

Humidity

Aim for 50 to 70% (Tree of Life) or 60 to 70% (LafeberVet) ¹². Mist daily and let the tank dry somewhat between mistings. Stagnant, overly wet conditions breed skin infections, so keep good ventilation ¹². Water must be free of chlorine, chloramine and other contaminants. Use a dechlorinator or filtered tap water, never distilled water ²⁴.

Substrate

Coconut fiber, cypress mulch or a bioactive mix, topped with sphagnum moss or leaf litter, holds humidity without molding ¹. Avoid gravel and other loose bits a frog could swallow ¹. Keep the substrate damp but not waterlogged ².

Diet & supplementation

• Variety. Gut-loaded insects such as silkworms, hornworms and black soldier fly larvae ¹².
• Treats only. Waxworms and mealworms, which are high in fat ¹.
• Schedule. Feed juveniles daily and adults two to three times a week. Tree of Life says three to four times a week for adults ¹².
• Supplements. Tree of Life suggests calcium 2–3 times a week plus a multivitamin once a week ¹. Unsupplemented insect diets cause metabolic bone disease ⁶.
• Clean up. Remove uneaten insects after a few hours ¹.

Handling & temperament

Calm, but their skin absorbs chemicals, so handle as little as possible ¹². When you must, use wet hands rinsed free of soap or moistened powder-free gloves ¹². Frightened frogs can give a loud distress call ³. Wash your hands after any contact, because amphibians can carry Salmonella ⁷.

Health

Common issues

• Obesity from overfeeding ¹.
• Red leg and other skin infections, tied to poor hygiene, dirty water and stale air ¹⁵.
• Metabolic bone disease. Soft or deformed jaw, fractures and a curved spine ⁶.
• Dehydration if humidity or water access lapses ¹.

Frogs shed and eat their skin regularly, and they look cloudy just beforehand. That's normal ².

When to see a vet

Poor husbandry can lead to skin disease that kills quickly ². See an amphibian vet promptly for red legs or belly, skin color changes, weakness, loss of balance, appetite or weight loss, or a soft jaw ⁵⁶.

Breeding overview

White's tree frogs often mature in their second year ²³. Males call during the breeding season and grow dark nuptial pads on their thumbs ²³. In the wild, breeding follows the summer rains ³.

Legal & ethics

Wild populations are generally healthy, but pollution, habitat loss, pets such as cats and the international pet trade all take a toll ³. Buy captive-bred frogs, and never release a pet.
