Setup
The numbers
Thermal gradient
Day: a real gradient, 30–31°C warm against 21–24°C cool, so the animal chooses. Night: 21–24°C.
Why
Same scale on every sheet here, so two species compare by eye.
The sheet stateswarm 30-31 °C / cool 21-24 °C / night 21-24 °C
Humidity
The sheet states40-60 %
UVB
The sheet statesFerguson Zone 2 reptile, which means that they need a UVI of 2.0-3.0 in the basking area
Traceable. The figures above appear in the page we cite, which we opened on 10 Aug 2026. That means you can check them, not that we have confirmed they are right. reptifiles.com
Drag the sun. The sheet states a night temperature, so the rail follows it.
Enclosure and conditions
Enclosure
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 ».
The sheet statesBaby (<2' / 60cm) Imperial: 2' x 1.5' x 1.5' / Metric: 60 x 45 x 45cm; Juvenile to Subadult (2' to 5') Imperial: 4' x 2' x 2' / Metric: 120 x 60 x 60cm; Adult (6' to 8') Imperial: 6' x 3' x 3' / Metric: 1.8 x 0.9 x 0.9m; Large adult (>8') Imperial: 8' x 4' x 4' / Metric: 2.4 x 1.2 x 1.2m
What your climate adds
This sheet states a range to hold. Your local climate decides how much work holding it is. Pick the nearest city: nothing is sent anywhere, the choice stays in this browser.
What it needs
Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation.
Food
Diet
Feeding rhythm
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 statesMice, Rats, Hamsters, Gerbils, Guinea pigs, Young rabbits, Chicks, Quail; Hatchlings and juveniles (no longer than 3′): Every 7-10 days; Subadults (longer than 3′): Every 14-20 days; Adults (no longer growing): Every 21-28 days

Identity
CITES I is a global listing and holds in every country. 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
What is its temperament like?
One of the calmest boas. Most are slow, steady and very tolerant of handling once they are settled.
How big does it get?
Usually around two metres but very heavy-bodied, so plan for a wide enclosure with plenty of floor space.
Does it climb?
Not much, it is a ground snake. Floor area, hides at both ends and a large water bowl matter more than height.
Are there any import restrictions I should know about?
This species is regulated internationally, so always buy with the correct paperwork and keep your documents. Ask the seller to show you theirs.

What this sheet states
This sheet states 6 of 7 of the fields this product runs on. What is missing turns something off: 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.
