Setup
The numbers
Thermal gradient
Day: a real gradient, 27–32°C warm against 21–27°C cool, so the animal chooses. Night: 24°C.
Why
Same scale on every sheet here, so two species compare by eye.
The sheet stateswarm 27-32 °C / cool 21-27 °C / night 24 °C
Humidity
The sheet states70-80%, and no lower than 60%
UVB
The sheet statesArcadia Desert 12%, 46" or Zoo Med Reptisun T5 HO 10.0, 46"; basking branch 12-13" below the lamp over mesh, 20-22" below if mounted inside
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. 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 6'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 statessnails (captive-bred only), mealworms, superworms, dubia roaches, grasshoppers, hornworms, earthworms, crawfish, shrimp, whole fish (tilapia, salmon, pollock), frozen rodents, eggs; younger than one year fed daily, after that 2-3x/week
The species
Identity
CITES 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
What does it eat? It looks like it needs something special.
Mainly snails, which it cracks with those broad back teeth. You need a reliable snail supply, plus some fish and prawn.
Does it bite?
Those jaws are built to crush snail shells, so a bite is no joke. Most stay calm if you do not grab them, but treat it as a hands-off animal.
What setup does it need?
A big enclosure that is half land and half water, with a pool it can fully submerge in, a basking branch above it and strong filtration.
Is it difficult?
Yes, one of the harder lizards. The water needs constant cleaning and the snail diet is expensive, so it is not a first lizard.

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.
