Did you know? White's tree frogs are also called 'dumpy tree frogs' because they develop adorable fat rolls (fatty ridges above the eardrums) as adults. A modest ridge is normal in an adult, but one that sags or folds over the eardrum is the classic sign of an overfed frog.

The first week

The numbers a new owner needs in the first week, each from the article it links to. Rows with no link come from the encyclopedia.

Enclosure: 18 by 18 by 24 inches tall minimum for one adult, or 24x18x24 for a group of two to four of similar size. A frog swallows anything that fits, smaller frogs included.Setup guide →
Temperature: Cool side 70 to 75°F, basking 80 to 85°F, mid-70s at night. A gentle gradient, not intense heat.Setup guide →
Humidity: 50 to 60% baseline with misting spikes to 70 to 80% once or twice daily, then a dry-down. Constant high humidity is what brings bacterial and red-leg problems.Setup guide →
Water: Dechlorinated tap or spring water only, never distilled or reverse-osmosis, which are not electrolyte-balanced and can kill an amphibian.Setup guide →
Substrate: Coarse orchid bark, coco fiber or husk, or a bioactive mix, lightly moist. Nothing fine enough to swallow while feeding.Setup guide →
UVB: Recommended: a low-output 5% T5 HO tube with the basking branch at least 6 inches below it, replaced every 6 to 8 months on schedule.Setup guide →
Feeding: 3 to 4 insects, 2 to 3 times a week for an adult, never free-fed, with waxworms and superworms once a week at most.Health guide →
Obesity check: Fat bulging over the tympanum and in the armpits, not general roundness, is the line between the natural dumpy look and a problem.Health guide →
Handling: Short and infrequent, with hands washed in plain water only, no soap, or in wet powder-free vinyl gloves (nitrile second, never latex).Handling guide →
Cover: Broad-leaved live plants at several heights so it can sit supported and unseen; artificial ones fill the dense parts but do not do the humidity. Always immediately visible means not enough in there.Enrichment guide →
Budget: $20 to $60 for the frog, $305 to $595 for the setup, $355 to $745 with the first vet exam, then $150 to $245 a year in supplies, about $10 to $25 a month. An exam runs $50 to $150, an exotic emergency fee from around $250.Cost guide →
Lifespan: About 16 years on average, one recorded at 21; conservative figures say 10 to 15-plus.Cost guide →
Adult size: 3 to 4.5 inches (7 to 11 cm).
Quarantine: Six to eight weeks, resetting if illness shows partway. Zoos run a 30-day minimum with 60 preferred.Quarantine guide →
Moving a new arrival: In a small clear container with some of its own water, never a net, so it is never touched or forced through mesh.Quarantine guide →
Hygiene: A healthy-looking amphibian sheds Salmonella, by hands and surfaces to mouth. Children younger than 5 do not touch amphibians or their environments.Hygiene guide →

Emergency card

Call the vet now if you see any of these.

Lethargy and weight loss in a new or suspect animal: chytridiomycosis, quarantine it and get to a vet
Redness on the belly and legs with lethargy and appetite loss: red-leg syndrome
Skin lesions or a bacterial infection, which a wet, poorly ventilated enclosure invites
Weak limbs, a droopy jaw, or twitching: calcium or UVB catching up with the frog
Fat bulging over the tympanum and armpits: obesity, a diet fix at home, and a vet once the liver is involved

The 18x18x24 minimum, the temperature gradient, the humidity that dips instead of sitting high, substrate, UVB, and the water that is safe to mist with.

How to Handle a White's Tree Frog

Why plain water beats soap, when gloves are the safer option, how long a session runs, and why the risk points at the frog rather than at you.

Common White's Tree Frog Health Issues (Obesity Is the Signature Risk)

Obesity as the signature risk, chytridiomycosis, red-leg syndrome, bacterial and skin infections, metabolic bone disease, and the husbandry pattern behind all of them.

Which insects to offer, how often by size and age, gut-loading and dusting, and the ridge test that shows overfeeding before the frog does.

18x18x24 in+ arboreal terrarium (24x18x24 for a small group of two to four)

Coarse orchid bark, coco husk, or a bioactive soil mix

Broad-leafed live plants, with artificial foliage filling out the dense parts

Artificial foliage for the dense parts

Cork bark and PVC pipe hides

Sturdy climbing branches and broad leaves or platforms, mounted high

Shallow water dish that's easy to keep clean

Low-output UVB (T5 HO 5%)

Plug-in timer for the lights

Side-mounted heat mat with a thermostat

Digital thermometer and hygrometer

Water conditioner/dechlorinator

Fine mist spray bottle

Calcium dust and a multivitamin; the calcium carries D3 only when the frog has no UVB

Frequently Asked Questions

What humidity level is correct for a White's tree frog?

Hold a baseline of 50 to 60% and let misting push it to 70 to 80% once or twice a day, then let it fall. Humidity that never drops is linked to bacterial and red-leg issues, so damp around the clock is the thing to avoid.

How long do White's tree frogs live, and how does that affect budgeting?

The average is about 16 years, and one individual reached 21 in human care. More conservative figures run 10 to 15-plus years. Either way, plan on well over a decade of ongoing care.

Is it safe to handle a White's tree frog?

Yes, more so than the great majority of frog and toad species kept as pets. They're docile, slow-moving, and tolerate handling well once they're used to it. The risk isn't the frog hurting you, it's accidentally harming the frog through chemical exposure on your hands.
