| Lifespan: | 5–8 Years (Up to 10 in optimal conditions) |
🏗️ Cage Requirements & Structural Standards
Red-Eyed Tree Frogs (Agalychnis callidryas) are strictly arboreal amphibians from the neotropical rainforests of Central America. They require significant vertical space and large, broad leaves for sleeping.
Minimum Enclosure Dimensions:
- Juveniles: 12" x 12" x 18" Front-opening enclosure.
- Adults (1 to 2 Frogs): 18" x 18" x 24" is the minimum standard for adults. Larger is always better for establishing a proper microclimate.
Fill the enclosure with smooth climbing vines, bamboo, and broad-leafed plants (like Monstera, Pothos, or large Bromeliads). During the day, they will adhere themselves tightly to the underside of these leaves to sleep in the shade.
Red-Eyed Tree Frogs can be housed in small groups (e.g., one male and multiple females, or a group of females) ONLY IF the enclosure is adequately large. However, NEVER house males together in a cramped tank as they will aggressively wrestle and stress each other. Additionally, NEVER house frogs of vastly different sizes together, as larger frogs will readily cannibalize smaller ones.
☀️ The UVB Standard (Cryptic Forest Dwellers)
Red-Eyed Tree Frogs are strictly nocturnal and spend their days sleeping under heavy foliage. However, ambient, low-level UVB filtering through the canopy is highly beneficial for their immune system, color vibrancy, and calcium metabolism.
Ferguson Zone Classification:
- ★ Zone 1 (Tree Frogs): Shade/Crepuscular dwellers. Mid-day UVI target of 0.4 to 0.7 (Maximum 1.0).
- Zone 2: Partial shade dwellers (Occasional baskers).
- Zone 3: Open or partial sun baskers.
- Zone 4: Full sun baskers (Extreme desert species).
UVB Requirements:
- Type: T5 HO (High Output) Linear Tube.
- Strength: 2.4% to 7% (e.g., Arcadia ShadeDweller) resting on the screen mesh.
- Coverage: The bulb should span no more than 1/2 of the enclosure top, ensuring they can escape the light entirely if they choose.
Note: Amphibian skin is highly permeable and sensitive to radiation. Ensure the frogs have plenty of thick shade and never mount a bare UVB bulb inside the enclosure without a screen filter.
🌡️ Temperature & Humidity Gradients
| Requirement | Specification |
|---|---|
| Warm Ambient (Canopy) | 82°F - 84°F |
| Cool Ambient (Floor) | 75°F - 78°F |
| Humidity Baseline | 60% - 80% (Requires a daytime dry-out period) |
| NIGHTTIME DROP | Temperatures MUST drop to 68°F - 72°F at night. |
| CRITICAL HEAT WARNING | NEVER exceed 85°F. They will rapidly dehydrate and die. |
Water Quality Standards:
All water used for misting or in their water bowl MUST be treated with a high-quality water conditioner (like ReptiSafe) to remove chlorine, chloramines, and heavy metals. Tap water is toxic to amphibians.
🦗 Nutrition: The Nocturnal Hunter
Red-Eyed Tree Frogs are strict insectivores. They hunt at night, meaning food should be offered just as the lights turn off to align with their natural circadian rhythm.
Feeding Schedule
| Age Group | Frequency | Quantity |
|---|---|---|
| Juveniles (Under 1.5 inches) | Daily | 3-5 appropriately sized insects |
| Adults (Over 1.5 inches) | Every 2-3 Days | 4-6 appropriately sized insects |
🦗 The Live Diet Roster
| Category | Food Options |
|---|---|
| Primary Staples | Crickets and Dubia Roaches (They prefer climbing insects). |
| Secondary Staples | Silkworms, Black Soldier Fly Larvae (NutriGrubs). |
| Hydrating Treats | Small Hornworms (Excellent for extra hydration). |
Calcium & Vitamin Supplementation
Because they are nocturnal and fast-growing, precise supplementation is key to preventing bone deformities.
- If using UVB: Dust insects with pure Calcium (NO D3) at most feedings, and a Multivitamin with low D3 once a week.
- If NO UVB is used: Dust insects with Calcium containing D3 at most feedings, alternating with a multivitamin once a week.
*Note: Insects should be no larger than the space between the frog's eyes to prevent choking.
🌿 Substrate Safety & Cleanliness
Because the enclosure requires heavy daily misting, the substrate must hold moisture well, resist mold, and support a clean microclimate.
Recommended Moisture-Retaining Options:
- ABG Mix (Atlanta Botanical Garden): The absolute best choice for tropical, damp setups. It drains beautifully and supports live plants and cleanup crews.
- Coconut Coir / Eco-Earth: Holds humidity exceptionally well.
- Leaf Litter (Mandatory): Regardless of your soil mix, covering the surface with a layer of boiled/baked oak or magnolia leaves prevents the frogs from accidentally ingesting dirt when they hunt on the floor.
Bioactive Setups:
A bioactive enclosure is highly recommended for this species. Adding a robust "Cleanup Crew" of tropical isopods (like Dwarf Whites) and springtails will break down frog waste and mold, which is crucial for sensitive amphibian skin.
- Sphagnum Moss: While great for humidity, loose strands of moss pose a severe choking and impaction hazard if accidentally ingested when the frog lunges for a cricket. Use it cautiously or keep it covered.
- "Toxing Out": Frogs absorb everything through their skin. If the substrate is allowed to become swampy, stagnant, or filled with feces, the frog will absorb the toxic buildup and suffer fatal organ failure. Spot cleaning and proper drainage are non-negotiable.

👆 Hover or tap the cards below to reveal the answers!
Why are its eyes so red?
Hover to RevealThis is a defense mechanism called Startle Coloration. When a predator approaches a sleeping frog, it wakes up and suddenly flashes its bright red eyes and blue/yellow sides, temporarily confusing the predator so the frog can escape.
Why is it sleeping all day?
Hover to RevealThey are strictly nocturnal! During the day, they tuck their bright limbs under their bodies, close their eyes, and camouflage as a green lump on the underside of a leaf. They will wake up when the lights go out.
Why did it turn dark brown/purple?
Hover to RevealRed-Eyed Tree Frogs change color! They are typically bright green when sleeping during the day. At night, when they are active and hunting, their skin naturally shifts to a dark reddish-brown or purple to camouflage in the dark.
Can I hold my frog?
Hover to RevealNo. Amphibians have highly permeable skin. The natural oils, salts, and soaps on human hands are toxic to them. If you must move them, use powder-free nitrile gloves or coax them into a plastic cup.
Do they need a swimming pool?
Hover to RevealNo! They are arboreal tree frogs, not aquatic swimmers. Provide a water dish that is only deep enough to reach their chin so they can safely soak and absorb water through their belly without drowning.
Why is my frog making a "chucking" noise?
Hover to RevealThat is the mating call of a male! Males will inflate their vocal sacs and make a rhythmic "chuck-chuck" noise at night to attract females or establish territory.
What are the gold lines in its eyes?
Hover to RevealRed-eyed tree frogs have a specialized inner eyelid called a nictitating membrane. This transparent membrane has a gold, tiger-stripe pattern that allows them to see predators while still protecting and hiding their bright red eyes as they sleep.
Why does my frog look bloated?
Hover to RevealIf they look like a balloon, it could be "Toxic Out" syndrome (organ failure from dirty substrate/water), or they may simply be holding water before releasing urine. Check your husbandry immediately.
