Keeping one

11 ft 5 in × 11 ft 5 in × 7 ft 2 in(348 × 348 × 217 cm)

Minimum length × width × height, for one animal. Bigger is always better. Substrate at least 17 in (44 cm) deep.

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

Burrows, so substrate deep enough to dig in matters as much as floor area.

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 2 ft 10 in (869 mm), at 4 × 4 × 2.5 times it, following the German federal welfare standard — how this is worked out.

No preferred body temperature has been recorded for Coral Cylinder Snakes. Rather than repeat a number from a care sheet, this page leaves it out.

Feeding

A prey item should be no wider than the space between the animal's eyes.

Widely used across reptile husbandry references. The stated reason is that the gap approximates the width of the throat, so wider prey is associated with impaction. This is established practice, not a measurement.

27kJ per day

Worked out for an animal of 260 g, the heaviest recorded for Coral Cylinder Snakes — 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.
