The bar is the rank itself: its length is the share of the family this animal exceeds. The chart below is the family’s real spread, on a logarithmic scale because body length here runs from 16.5 to 165 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one

Land
43 × 21cm
Water, at least 9 cm deep
9 × 4cm

Minimum, and for two animals — which is how the standard states it. Bigger is always better. Around 43 cm tall on average.

The standard gives 10 × 5 body lengths of land and 2 × 1 of water, for two animals.

For each further animal the standard asks for another 9 × 9 cm of land and 4 × 4 cm of water.

Swiss Tierschutzverordnung (TSchV), SR 455.1, Anhang 2, Tabelle 6 — legally binding minimum enclosure sizes for amphibians, given as multiples of total body length and stated for two animals.

From this animal’s own snout-vent length, which for a frog is its body length of 1.75 in (42.8 mm) — how this is worked out.

Assam Treefrog

Feeding

1kJ per day

Worked out for an animal of 7 g, the heaviest recorded for Assam Treefrog — so it is the top of the range, not a figure for a particular animal. Weigh yours and the number will be lower.

An upper estimate, not a feeding target, and not veterinary advice. The equation covers only what an animal burns staying alive, so a growing, gravid or recovering animal needs more — and it was measured on wild animals, which move far more than one in an enclosure. Body condition and a vet who knows the species are what a feeding decision should rest on. Where this comes from.

What nobody knows

These are not gaps in our research. No scientific dataset records them for this species — and saying so is information you cannot get from a reference that simply leaves a field out.
