White Tree Frog Care Guide: Complete Setup & Feeding Tips 2025
White tree frogs, scientifically known as Litoria caerulea, have captured the hearts of amphibian enthusiasts worldwide with their charming “smiling” appearance and docile temperament. These robust Australian natives, also called dumpy tree frogs or Australian green tree frogs, make excellent pets for both beginners and experienced keepers due to their hardy nature and relatively simple care requirements.
Understanding White Tree Frogs: Species Overview
Physical Characteristics and Natural Behavior
White tree frogs are among the largest tree frog species commonly kept in captivity, reaching 3-5 inches in length. Their distinctive appearance includes bright green to blue-green coloration, horizontal pupils (unlike most tree frogs with vertical pupils), and the characteristic fatty ridges above their eyes that become more pronounced with age.
These arboreal amphibians are naturally nocturnal, spending daylight hours hidden in tree hollows, leaves, or human structures like toilet tanks and water pipes in their native Australia and New Guinea. Their remarkable adaptability allows them to survive in various environments, from tropical forests to more arid regions, by secreting a waxy coating that prevents dehydration.
Lifespan and Size Expectations
With proper care, white tree frogs can live 15-20 years in captivity, with some specimens reaching over 25 years. Females typically grow slightly larger than males, with adult size ranging from 3-5 inches snout-to-vent length. Sexual maturity occurs around two years of age, when males develop dark nuptial pads on their thumbs and begin vocalizing.
Essential Tank Setup Requirements
Terrarium Size and Specifications
A properly sized enclosure is crucial for white tree frog health and well-being. For housing one to two adult frogs, the minimum recommended dimensions are 18″L x 18″ W x 24″H, though larger is always preferable. Vertical space is particularly important since these arboreal species spend most of their time climbing and perching.
For multiple frogs, expand upward rather than outward—an 18″x18″x36″ terrarium can comfortably house 2-3 adult specimens. Glass terrariums with front-opening doors work best, providing easy access for maintenance while maintaining proper humidity and temperature gradients.
Substrate Selection and Setup
The substrate choice significantly impacts both frog health and maintenance requirements. Bioactive substrates offer the best long-term solution, utilizing beneficial bacteria and cleanup crews to process waste naturally.
Recommended Bioactive Mix:
- Base layer: Expanded clay balls or aquarium gravel (drainage)
- Barrier layer: Fine mesh or landscape fabric
- Active layer: Organic potting soil mixed with coconut fiber and sphagnum moss
- Top layer: Leaf litter (oak or beech leaves)
This layered approach prevents waterlogging while maintaining appropriate moisture levels throughout the substrate profile. Non-bioactive alternatives include coconut fiber (Eco Earth) or cypress mulch, though these require more frequent spot-cleaning.
Essential Equipment and Environmental Controls
Heating Requirements:
Maintain temperatures between 75-82°F during the day with a nighttime drop to 70-75°F. Use a thermostat-controlled under-tank heater on one side to create a thermal gradient, avoiding overhead heat sources that can reduce humidity.
UVB Lighting:
While white tree frogs can survive without UVB, providing low-level UVB lighting (Arcadia ShadeDweller or Zoo Med ReptiSun 5.0) significantly improves their health, calcium metabolism, and natural behaviors. Position the basking area 6-8 inches below the UVB source.
Humidity and Ventilation:
Target humidity levels of 60-70% with good ventilation to prevent stagnant air. Daily misting and a large water bowl help maintain these levels, while proper ventilation prevents fungal growth.
Furnishing and Enrichment
Create a naturalistic environment with horizontal perches, cork bark, artificial or live plants, and multiple hiding spots. Diagonal branch placement allows frogs to thermoregulate by choosing their preferred height and temperature zone.
Live plants like pothos, philodendron, and snake plants thrive in terrarium conditions while providing natural humidity regulation and visual barriers. Ensure all decorations are amphibian-safe and easily cleaned.
Feeding and Nutrition Guide
Dietary Requirements and Food Selection
White tree frogs are strict insectivores requiring varied diets for optimal health. Their natural diet consists of moths, beetles, locusts, and other flying insects, which should be replicated in captivity through diverse feeder insect offerings.
Primary Feeder Insects:
- Crickets (appropriately sized)
- Dubia roaches (0.25-0.5″ for juveniles, 0.75-1″ for adults)
- Black soldier fly larvae
- Silk worms
- Locusts
Occasional Treats:
All feeder insects should be gut-loaded 24-48 hours before feeding with commercial gut-loading products or fresh vegetables to enhance their nutritional value.
Feeding Schedules and Portion Control
Juvenile Feeding (under 2 years): Feed daily with 3-4 appropriately sized insects
Adult Feeding (2+ years): Feed 2-3 times weekly with 4-6 insects per feeding
Portion control is critical as white tree frogs are prone to obesity, which can cause eye problems and reduce lifespan. Food items should be no larger than the space between the frog’s eyes.
Supplementation Protocol
Calcium Dusting: Dust insects with calcium powder (without phosphorus) 2-3 times weekly for juveniles, 1-2 times weekly for adults
Multivitamin: Use a comprehensive reptile multivitamin once weekly
Rotate between calcium-only and calcium with D3 supplements, especially if not using UVB lighting.
Health Monitoring and Common Issues
Signs of a Healthy White Tree Frog
Monitor your frogs daily for these positive health indicators:
- Clear, bright eyes without cloudiness
- Smooth, moist skin free of cuts or discoloration
- Active hunting behavior during evening hours
- Regular eating and waste production
- Proper posture and climbing ability
Common Health Problems and Prevention
Obesity: The most frequent issue in captive white tree frogs, leading to lipid deposits over the eyes and potential vision problems. Prevent through proper portion control and feeding schedules.
Metabolic Bone Disease (MBD): Affects juveniles primarily, caused by inadequate UVB, calcium deficiency, or improper calcium-to-phosphorus ratios. Symptoms include skeletal deformities, weakness, and fractures.
Bacterial Infections: Often result from poor water quality or substrate conditions. Red-leg syndrome presents as redness on the limbs and requires immediate veterinary attention.
Respiratory Infections: Manifest as wheezing, lethargy, or open-mouth breathing, typically caused by excessive humidity or temperature fluctuations.
Veterinary Care and Emergency Protocols
Establish a relationship with an exotic veterinarian experienced in amphibian care before problems arise. Emergency situations requiring immediate attention include:
- Difficulty breathing or mouth breathing
- Lethargy lasting more than 24 hours
