American green tree frog
Hyla cinerea · also called American green tree frog, green tree frog, green treefrog
American green tree frogs are small, vivid green arboreal amphibians native to the southeastern United States. They are visually appealing display animals, best observed rather than handled.

Part of the Tree Frogs
Arboreal frogs adapted to climbing with expanded toe pads, kept in tall, planted, humid terrariums. Most are nocturnal display animals that should be handled minimally and only with clean, wet hands to protect their sensitive, absorptive skin.

Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Habitat & enclosure
American green tree frogs are small, arboreal amphibians best kept in a vertically oriented, planted vivarium with live or artificial plants, climbing branches, and broad leaves to perch on. A soft, moisture-retaining substrate (such as coco fiber, sphagnum moss, or a bioactive mix) and a shallow dish of dechlorinated water support the humidity and hydration these frogs need.
Maintain comfortable, moderate ambient temperatures with a slight nighttime drop and a humid (but not waterlogged) environment. A low-output UVB source on a regular cycle is recommended, since UVB supports the vitamin D3 pathway and calcium metabolism that prevent metabolic bone disease.
Water quality is critical because amphibian skin is highly permeable: only dechlorinated, amphibian-safe water should ever contact them, and the enclosure should be kept clean. Some states regulate collection of native amphibians, so source captive-bred animals and check local laws.
Substrate
Use a moisture-retaining substrate such as coconut fiber, sphagnum moss, or a bioactive soil mix that holds humidity without staying waterlogged. Add a shallow, easily-cleaned water dish of dechlorinated water large enough for soaking.
Equipment & setup
House these arboreal frogs in a tall enclosure at 72-80F daytime with a slight night drop, using a low-wattage heat source if the room is cool, and maintain 50-70% humidity via misting. Provide plenty of vertical branches, cork bark, and broad-leaf plants for climbing, plus low-level (2.0-5.0) UVB lighting on a day-night cycle.
Diet
Green tree frogs are insectivores fed a variety of appropriately sized live insects — commonly crickets and small roaches, with items like black soldier fly larvae adding variety and the occasional wax worm offered sparingly as a richer treat. Variety helps balance nutrition over time.
Feeder insects should be dusted with a calcium supplement (and a multivitamin on an appropriate schedule for amphibians) to support bone health and prevent metabolic bone disease; the specifics are best guided by an amphibian-experienced veterinarian rather than guessed. Gut-loading the feeders before offering them improves their nutritional value.
Avoid wild-caught insects, which can carry pesticides and parasites. Provide a shallow dish of dechlorinated water at all times, as frogs absorb water (and, unfortunately, contaminants) through their skin.
Behavior & temperament
Green tree frogs are nocturnal and arboreal, spending the day tucked against leaves or glass and becoming active to hunt after dark. They are generally tolerant of being kept in compatible groups, though males call loudly, particularly in breeding condition — a charming or disruptive trait depending on the household.
They are display animals, not handling pets. Their permeable skin readily absorbs oils, soaps, lotions, and salts from human hands, so handling should be minimal and, when necessary, done with clean, wet (dechlorinated) hands or a soft container. This is a welfare issue as much as a behavioural preference.
Watching their colour shift — from bright lime to duller brown depending on temperature, humidity, and mood — is part of the appeal, and a settled frog in good conditions will perch contentedly in the open at night.
Health
Care should be anchored to a reptile/amphibian-experienced veterinarian, and because frogs are subtle, owner observation of skin colour and texture, body condition, appetite, and behaviour is the main early-warning system. Clean conditions and dechlorinated water are the most important preventive measures.
Documented amphibian concerns include chytrid fungal infection (a serious disease of amphibians worldwide), bacterial 'red-leg' (reddening of the legs and underside, with swelling and lethargy), parasites, and metabolic bone disease where calcium or UVB is inadequate. These require veterinary diagnosis and care.
Signs that warrant prompt evaluation include lethargy, abnormal skin colour or lesions, bloating, reddened limbs, and persistent inappetence. Because amphibians decline quietly and their skin is so sensitive, prompt professional input is preferable to home experimentation.
Tips, DIY & hacks
Mist in the evening to mimic their nocturnal activity and trigger feeding, and dust crickets and other insects with calcium and a multivitamin. PVC pipe sections and bamboo make cheap vertical perches and hides; quarantine wild-caught individuals and watch for the loud 'quack' call from males, which signals breeding readiness.
Origin & history
The American green tree frog (Hyla cinerea) is native to the southeastern United States, where it is a common, vocal resident of wetlands, marsh edges, and backyards; it is the official state amphibian of Georgia and Louisiana. Its bright colour, manageable size, and hardiness made it a familiar entry-level display amphibian.
Animals in the trade are a mix of captive-bred and wild-sourced, and because some states regulate the collection of native amphibians, responsible keepers favour captive-bred frogs and check local wildlife regulations before acquiring them.
Anecdotes & owner lore
Community experience and cultural notes — not veterinary advice. Every animal is an individual; treat these as colour, not care instructions.
Across the American South, the green tree frog is the sound of a summer night — a nasal, repetitive 'quonk… quonk' chorus from the marsh edge that residents associate with warm, humid evenings, and an old folk nickname casts the frog as a 'rain frog' whose calling foretells a storm. Many a Southerner's first frog encounter is one stuck to a porch window, hunting moths drawn to the light.
Keepers love the species' mood-ring colour changes and its habit of plastering itself flat against the glass in odd, comical poses. The recurring piece of advice newcomers receive is hands-off appreciation: these are frogs to watch glowing green under a night light, not to handle, and that restraint is itself part of the hobby's culture of respecting delicate amphibian skin.
Common ailments
- Metabolic bone disease (MBD) — common — Prevented with dusted/gut-loaded feeders and low-output UVB; calcium and vitamin D3 balance is the key.
- Parasitic infection — common
- Chytrid fungus (chytridiomycosis) — rare — Green tree frogs are relatively resistant post-metamorphosis, but biosecurity still matters in a collection.
- Red-leg syndrome (bacterial septicemia) — rare
