Setup
The numbers
Thermal gradient
Day: a real gradient, 41°C warm against 24–31°C cool, so the animal chooses. Night: 21°C.
Why
Same scale on every sheet here, so two species compare by eye.
The sheet stateswarm 41 °C / cool 24-31 °C / night 21 °C
Humidity
The sheet statesmaintained around 60%
UVB
The sheet statesArcadia Desert 12%, 46" or Zoo Med Reptisun T5 HO 10.0, 46"; 17-18" below the lamp
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. dubiaroaches.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 statesabsolute minimum 8'L x 4'W x 4'H for a single rhino iguana
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 statesherbivores, plant-based diet: Leafy greens daily, Vegetables every other day, Fruit 3x/week, Commercial diet 3x/week
The species
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
Is it dangerous?
A big adult can bite hard enough to need stitches and the tail whip hurts. They tame down, but a careless adult male is genuinely risky.
How long does it live?
Often thirty to fifty years. Plan for who takes it if your life changes.
What does it eat?
Almost all greens, flowers and vegetables. Very little animal protein, because too much protein harms them long term.
Do I need paperwork?
Yes, it is a CITES-listed species, so buy only with proper documents and keep them. We hand the papers over with the animal.

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.
