Longer than 57% of all colubrid snakes anyone has measured.
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 98 to 3,800 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

The pregnancy was in its final stage since the offspring were fully formed. Offspring presented an average body mass of 2.02 g ± 0.27 standard deviation (SD) (1.46–2.34 g, n = 10). The smallest offspring measured 179 mm total length (female) and the largest 195 mm total length (male)" (de Faria et al. 2021, their SVLs are 174.7-190.6)

Keeping one
2 ft 6 in × 15 in × 3 ft 9 in(76 × 38 × 114 cm)
Minimum length × width × height, for one animal. Bigger is always better.
The standard sizes snakes as a fraction of total length: 1 × 0.5 × 1.5.
Recorded both on the ground and climbing, so this is the larger of the two rules in every dimension.
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 total length of 2 ft 6 in (760 mm), at 1 × 0.5 × 1.5 times it, following the German federal welfare standard — how this is worked out.
No preferred body temperature has been recorded for Dryophylax almae. Rather than repeat a number from a care sheet, this page leaves it out.
Feeding
A prey item should be between the same width as the widest part of the snake's body and about 1.5 times that width.
Widely used across snake husbandry references. An alternative formulation gives prey at 10-15% of the snake's body mass. This is established practice, not a measurement.
9kJ per day
Worked out for an animal of 77 g, the heaviest recorded for Dryophylax almae — 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.
