18°Night

Day: a real gradient, 35°C warm against 21–26°C cool, so the animal chooses. Night: 18°C.

Why

Same scale on every sheet here, so two species compare by eye.

The sheet stateswarm 35 °C / cool 21-26 °C / night 18 °C

Not needed for this species

Stated in the sheet, not inferred.

The sheet statesA full spectrum UV light is not required for the maintenance of D. couperi, but it is recommended

Narrower than the page we cite. The source we cite, read on 10 Aug 2026, gives a wider range than the one above. The narrowing is ours and nobody here has written down why. reptilesupply.com

Drag the sun. The sheet states a night temperature, so the rail follows it.

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 ».

Food

Diet

Feeding rhythm

every 10 dAs an adult
2Meals in 28 days

Twenty-eight days, one row. Each band is a meal window. The sheet gives several ages on one line; this is the adult figure.

Why

The windows widen as they go because the interval is a range: four meals after a 10–14 day cycle land anywhere between day 40 and day 56.

The sheet statesrodent prey items; young fed weekly or three times biweekly, adults once a week or every 10 days

The species

National law is not global, and we hold no national wildlife law for any country, Thailand included. Check your own authority before buying or selling.

Questions & sources

Common questions

How much space does it need?

A lot. It reaches 2 to 2.5 metres and is constantly on the move, so it needs a custom room-sized enclosure.

Is it dangerous?

Not venomous, but it is big, fast and strong-jawed, and it swallows quickly around food. A serious bite is possible.

What does it eat and how much does it cost?

Rodents and a big appetite. Feeding this species costs more than any other colubrid on this site.

Is it tame?

Usually confident and calm rather than aggressive, but its strength means careful two-hand support and tong feeding.

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

UVB is measured but does not count: it is absent from 420 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.
