8–9 cmNose to tail, adult ♂

The size the sheet states for a grown animal. This sheet gives a figure per sex; the one drawn is marked.

Why

Two drawings, because they answer two questions. The silhouette is at true scale against a 1.75 m person: it says how big this animal actually is, which no number does for someone who has never seen one. The bar under it is logarithmic and shared by every sheet here, so a 2 cm isopod and a 4 m python both stay readable on the same axis and two species can be compared at a glance.

Adult size

How common this animal is

4,948Live individuals in declared US trade filings

NOT a measure of how many are kept. These filings count animals shipped for any purpose, including the food trade and laboratory supply, and they are United States records only. The three largest volumes in the source belong to a food frog, a bait species and the standard laboratory amphibian.

Drawn from the stated numbers. Only what the sheet states is drawn inside.

Why

The rectangle carries the exact width-to-height ratio of the figures above it, and the ruler under it places that width on the 0–250 cm scale every sheet here shares, so two species still compare at a glance. Nothing is added that the sheet does not name: a lamp drawn on a sheet that never mentions one would be invented equipment. What the sheet leaves out is listed rather than left blank, because an empty tank reads as « none needed ».

Reproduction

Life course

Day 0Hatch
8–15 yrLifespan in care
8 yrMinimum commitment
Sexual maturityNot in our data

Read from the lifespan and maturity the sheet states, for animals in care and not in the wild.

Why

The minimum commitment is the low end of that lifespan, and the reproductive window is what is left after maturity: both are subtractions on stated figures, not figures of their own.

Sexing
♀ larger; ♂ double vocal sac forming visible bilateral 'bulges' when calling
Maturity
18–24 months
Breeding trigger
Rainy season simulation: reduce photoperiod to 10 h and T° to 22 °C for 5–6 weeks, then gradually increase + intensive misting; tree hole filled with water
Egg laying
Spawning in water-filled tree holes (exclusive breeding site in canopy); 2 000–2 500 eggs; ♂ role = calling and axillary amplexus
Tadpoles / metamorphosis
Herbivorous-omnivorous; high density tolerated (gregarious species); metamorphosis 6–9 weeks
Juvenile care
Robust froglets; small crickets + D. hydei; moist arboreal vivarium

Common health problems

Sticky milky skin secretion under stress
Signsirritates eyes and mucous membranes — wash hands after handling
Chytridiomycosis (Bd)
SignsPCR recommended; sensitive species despite apparent robustness
Obesity if overfed
Signsration to 2×/week for adults
Quarantine
Signs30 days; arboreal vivarium; T° 25–27 °C; observe nocturnal activity (nocturnal species); appetite test D3

Good to know

  • Milky-white and very adhesive skin secretion under stress: defence against predators; no toxicity to humans but irritating to eyes
  • Breeds exclusively in tree holes in the canopy: installation of a hollow trunk or vertical PVC hide as spawning site is essential
  • Juveniles display a brown-white livery very different from adults (grey-blue banded): reassure buyers about the colour change

Common questions

How big do they get?

Large for a tree frog, comfortably filling your hand as an adult, so plan on a tall roomy tank with sturdy branches.

Is it loud?

Males have a deep resonant call that carries through a house. Very impressive, but not ideal next to where you sleep.

Why did it go all white and sticky when I picked it up?

That is a stress secretion. It is not dangerous but it is a clear sign to put the frog down, and you should wash your hands.

Do they need a water area?

Yes, a decent water container up in the tank suits them, since in the wild they breed in water-filled tree holes.

What it needs

A way to check the night figurebecause temp — 24-28 °C day; 22-24 °C night; tolerance 22-30 °C
A hygrometerbecause humidity — 60–80% (ventilation needed); peaks at 90% after misting; misting 1–2×/day

Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation.

What this sheet states

77%
TemperatureHumidityEnclosure sizeActivityOriginDietSourcesUVB

This sheet states 5 of 7 of the fields this product runs on. What is missing turns something off: day/night engine and awake count on the globe, the diet section. We show the gap rather than fill it with a plausible number.

UVB is measured but does not count: it is absent from 421 of 678 sheets, and on most of them that is not a gap, since a nocturnal snake's sheet has no reason to state a UV index. Counting it would call the library incomplete without cause.
