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 32 to 418 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one

2 ft 7 in × 19.5 in × 2 ft 7 in(80 × 50 × 80 cm)

Minimum length × width × height, for one animal. Bigger is always better.

The standard sizes climbing species at 4 × 2.5 × 4 times snout-vent length.

Lives in vegetation, so height and climbing structure matter more than floor space.

Mindestanforderungen an die Haltung von Reptilien (Sachverständigengutachten), German Federal Ministry for Nutrition, Agriculture and Forestry, Animal Welfare Division, 10 January 1997. The standard states these floor areas are recommendations rather than binding limits.

From this animal’s own snout-vent length of 7.75 in (200 mm), at 4 × 2.5 × 4 times it, following the German federal welfare standard — how this is worked out.

No preferred body temperature has been recorded for Two-marked ForestDragon. Rather than repeat a number from a care sheet, this page leaves it out.

Feeding

Prey size does not apply. A herbivore's diet is judged on fibre, on the ratio of calcium to phosphorus, and on avoiding plants high in oxalates.

The animal does not take prey items. This is established practice, not a measurement.

30kJ per day

Worked out for an animal of 288 g, the heaviest recorded for Two-marked ForestDragon — 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.
