Setup
The numbers
Thermal gradient
A real gradient, 32°C warm against 24–27°C cool, so the animal chooses. The sheet states no separate night figure.
Why
Same scale on every sheet here, so two species compare by eye.
The sheet stateswarm 32 °C / cool 24-27 °C
Humidity
The sheet states55-75%
UVB
The sheet statesZoo Med T5 HO ReptiSun 5.0 or Arcadia Forest 6% in a reflective T5 HO fluorescent fixture
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 statesat least 8'L x 4'W x 4'H
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.
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 and rats, African soft-furred rats, hamsters, gerbils, guinea pigs, young rabbits, chicks, quail, and Reptilinks; Newborn-18 months: once a week; 18 months to 4 years: every 2-3 weeks; 4+ years: every 4-8 weeks
The species
CITES I/II 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
How big does it get?
A true red-tail female commonly reaches around three metres and becomes very heavy. This is a big powerful animal, not a starter snake.
Is it safe to handle?
Juveniles are fine for one person. Once it is large we insist on a second adult present, because a big constrictor can overwhelm one pair of hands.
What is its temperament like?
Most captive-bred boas are calm and tolerant, which is why they are so popular. The risk is size, not attitude.
How much does it cost per month?
An adult eats a large rodent every week or two, so figure a few hundred baht a month for food plus the electricity to heat a large enclosure.

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.
