Red-eyed tree frogs are one of the most iconic frogs in the world, with bright green bodies, orange toes and vivid red eyes. They’re hugely popular in the hobby but a little more sensitive than some beginners’ frogs, so they’re best for keepers who can provide stable warmth, humidity and excellent enclosure design.

Quick Facts

• Common name: Red-eyed tree frog
• Scientific name: Agalychnis callidryas
• Adult size: 5–7 cm (around 2–3 inches)
• Lifespan: 8–12+ years with correct care
• Difficulty: Intermediate
• Activity: Strictly nocturnal; spend the day sleeping on leaves

Natural History

This species is native to the rainforests of Central America, where it lives high in the canopy on broad leaves above pools and streams. They experience warm temperatures, heavy rainfall and very high humidity, as well as plenty of cover from foliage.

Enclosure & Setup

• Minimum size: 45 × 45 × 60 cm vertical terrarium for a small group; larger is beneficial.
• Orientation: Tall, with plenty of climbing space and leaf surfaces for resting.
• Substrate: Moist soil or bioactive substrate over a drainage layer.
• Décor: A dense network of branches, cork tubes and live plants (pothos, bromeliads, philodendron) to provide sleeping leaves and hiding spots.

Temperature & Humidity

• Day temperature: 24–28 °C, with a gentle warm zone.
• Night temperature: 22–24 °C; avoid big drops.
• Humidity: 70–90%. Mist thoroughly each evening; allow partial drying during the day but never a bone-dry environment.

Excellent ventilation is essential. Aim for a warm, humid but airy environment rather than a stagnant, dripping box.

Lighting

Provide a moderate UVB tube across the top of the enclosure, with plenty of plant cover to create dappled light. A 12-hour light cycle works well. Plants will benefit from good quality LED or T5 lighting, which also helps create a natural day/night rhythm for the frogs.

Water & Hydration

• Use a large, stable water dish with dechlorinated water, or a shallow water area in the vivarium design.
• Change water daily and clean regularly to prevent bacterial build-up.
• Evening misting is crucial; frogs will often drink droplets from leaves.

Diet & Feeding

• Main foods: Crickets, roaches, suitably sized locusts, occasionally black soldier fly larvae and other soft-bodied insects.
• Feeding frequency: Juveniles every 1–2 days; adults 3–4 times per week.
• Supplements: Calcium on most feeds and a balanced multivitamin once or twice a week.

Offer food in the evening when the frogs are active. Monitor body condition carefully; underfeeding can be just as harmful as overfeeding.

Behaviour & Handling

Red-eyed tree frogs are delicate and easily stressed by excessive handling. Enjoy them primarily as display animals.

• Limit handling to essential maintenance.
• Never disturb sleeping frogs during the day without good reason.
• Use clean, wet hands or powder-free gloves to protect their skin.

Common Health Issues

• Dehydration: Usually due to inadequate humidity or lack of misting.
• Skin infections: Linked to poor hygiene or stagnant, mouldy conditions.
• Stress-related problems: Caused by excessive handling, bright lighting with no cover, or constant disturbance.

Is a Red-Eyed Tree Frog Right for You?

If you’re happy to build and maintain a lush, humid planted vivarium and mostly watch your frogs rather than handle them, red-eyed tree frogs are a stunning choice. They suit keepers who already have some basic amphibian experience or are prepared to research carefully and invest in high-quality equipment from day one.
