Red-eyed tree frogs ( Agalychnis callidryas ), also known as red-eyed leaf frogs, are admired for their striking appearance, marked by their vivid red eyes. These amphibians are native to the tropical jungles and rainforests of Mexico, Central America, and Colombia. Characteristically, they feature a green body, often accented with blue legs and sides, orange toes, and a white belly. This article delves into the specifics of their diet and nutritional needs, providing a complete guide for both enthusiasts and caretakers.
Understanding Red-Eyed Tree Frogs
Frogs, being amphibians, require specific environmental conditions and dietary provisions to thrive, differing significantly from reptiles. Red-eyed tree frogs, in particular, are arboreal, meaning they predominantly live in trees.
Habitat Requirements
An adult red-eyed tree frog requires a minimum 15-gallon enclosure, designed to be tall to accommodate their climbing habits. Maintaining the correct temperature and humidity is crucial for their well-being. Daytime temperatures should range from 68 to 70°F, with nighttime temperatures between 75 and 80°F. It is vital to ensure the habitat never exceeds 80°F. Daily temperature checks using thermometers placed in both warm and cool areas of the enclosure are recommended.
Humidity levels should be consistently maintained between 70-80%, monitored daily with a hygrometer. Access to a shallow, stable bowl of dechlorinated water, approximately 1-2 inches deep, is also essential for soaking.
The substrate should consist of a moisture-retaining material such as coconut fiber or moistened sphagnum moss, which helps maintain the necessary humidity. The habitat should include climbing structures and hiding areas, mimicking their natural environment. Dark-green paper or cork bark can be used to cover the rear wall of the enclosure. It is important to avoid overcrowding the tank, ensuring the frog has ample space to explore.

Social Behavior
Male red-eyed tree frogs exhibit territorial behavior and should not be housed together to prevent fighting. A single male can coexist with one or more females. When housing multiple frogs, they should be of similar age and size. Introductions should be gradual and closely supervised to ensure compatibility.
Handling Precautions
When handling frogs, disposable, non-powdered gloves moistened with dechlorinated water should always be worn. Frogs can carry infectious diseases, including salmonella, which is transmissible to humans.
Dietary Needs of Red-Eyed Tree Frogs
Red-eyed tree frogs are carnivores with a diet primarily consisting of insects. In the wild, they feed on crickets, flies, grasshoppers, and moths. Occasionally, they may also consume smaller frogs.
Feeding Practices
A varied diet of gut-loaded insects and worms is essential for maintaining the health of red-eyed tree frogs in captivity. Gut-loading involves feeding insects a nutrient-rich diet to enhance their nutritional value for the frog. Juvenile red-eyed tree frogs should be fed daily and given a calcium supplement with vitamin D to support their rapid growth. Adult frogs can be fed less frequently, typically every other day.
Red-eyed tree frogs are prone to overeating if given the opportunity, which can lead to obesity. Providing a variety of insects rather than relying on the same ones each day helps ensure a balanced intake of nutrients.

Supplementation
Before feeding, insects should be dusted with a powdered vitamin supplement to provide essential nutrients. This can be done efficiently by placing the insects in a bag or disposable container along with the supplement.
Nutritional Requirements
Ensuring that red-eyed tree frogs receive optimal nutrition is crucial for their health and longevity. Gut-loaded diets are fortified with vitamins and minerals, which help meet these requirements. Key nutrients include:
- Calcium: Essential for bone development and muscle function.
- Vitamin D: Aids in calcium absorption.
- Other Vitamins and Minerals: Support overall health and immune function.
Maintaining a Healthy Habitat
Maintaining a clean and well-maintained habitat is vital for the health and well-being of red-eyed tree frogs. Daily spot-cleaning to remove discarded food and droppings is necessary. A more thorough cleaning should be performed regularly:
- Using latex gloves moistened with dechlorinated water, move the frog to a secure habitat.
- Scrub the empty tank and furnishings with an amphibian-safe habitat cleaner or a 3% bleach solution.
- Leave the bleach solution on the habitat for at least 10 minutes to ensure proper disinfection.
- Rinse thoroughly and allow to dry before returning the frog to the clean habitat.
General Care Tips
- Handling: Handle red-eyed tree frogs only when necessary, using powder-free latex gloves moistened with dechlorinated water.
- Shedding: Amphibians shed their skin regularly, with some frogs shedding daily and others every few weeks.
- Record Keeping: Keep records of the frog's habitat, diet, and any supplements provided.
- Transportation: When transporting a frog, use a secure pet carrier or plastic container with ventilation holes. Place an inch of sphagnum moss on the bottom and mist the container to maintain humidity. Keep the temperature as close to the frog's normal habitat temperature as possible.
Common Health Issues and Prevention
Maintaining proper environmental conditions and providing a balanced diet are essential for preventing common health issues in red-eyed tree frogs. These issues can include:
- Nutritional Deficiencies: Resulting from an inadequate diet.
- Skin Infections: Caused by poor habitat hygiene or improper humidity levels.
- Stress: Due to improper handling or inadequate habitat conditions.
Red-Eyed Tree Frog FAQs
- Are red-eyed tree frogs poisonous? No, red-eyed tree frogs are not poisonous.
- Where do red-eyed tree frogs live? Red-eyed tree frogs are found in tropical rainforests in southern Mexico, Central America, and northern South America.
- How long can a red-eyed tree frog live? In captivity, red-eyed tree frogs typically live about 8-12 years.
Anatomy and Appearance
Red-eyed tree frogs are easily recognizable due to their big, bulging red eyes, a feature used as a defense mechanism known as "startle coloration." When the frog closes its eyes, its green eyelids help it blend in with the leafy environment. If approached while asleep, the sudden opening of its eyes can startle predators, providing the frog with a few seconds to escape.

These frogs have bright lime green bodies, sometimes with hints of yellow or blue, and can change to a dark green or reddish-brown color depending on their mood. They have white bellies and throats, with blue sides featuring white borders and vertical white bars. Their feet are bright red or orange. They are adept climbers with cup-like footpads that enable them to cling to leaves in the rainforest canopy.
Habitat and Distribution
First identified by herpetologist Edward Cope in the 1860s, the red-eyed tree frog is found in the lowlands and slopes of Central America and as far north as Mexico. They start life as tadpoles in temporary or permanent ponds and remain dependent on water to keep their skin moist. They stay close to water sources such as rivers in humid lowland rainforests, clinging to branches, tree trunks, and underneath leaves.
Threats to Red-Eyed Tree Frogs
Frogs are considered an indicator species, reflecting the health of their ecosystem. The world’s amphibian population has declined in recent years due to factors such as chemical contamination from pesticide use, acid rain, fertilizers, the introduction of foreign predators, and increased UV-B exposure from a weakened ozone layer, which can damage their fragile eggs.
