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
Identity
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.
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
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 it needs
Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation.

What this sheet states
This sheet states 5 of 7 of the fields this product runs on. What is missing turns something off: day/night engine and awake count on the globe, the diet section. We show the gap rather than fill it with a plausible number.
UVB is measured but does not count: it is absent from 421 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.
