Warm side: not in our data

The cool side, 21–29°C, dropping to 18–24°C at night. This sheet states the cool side only. It gives no warm side or basking figure, so the hot end is not in our data. Same scale on every sheet here, so two species compare by eye.

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

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

Not stated: The heat sourcethis sheet names only the cool side: « cool 21-29 °C / night 18-24 °C »
Not stated: The size of the enclosurethis sheet states no size

Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation. What the sheet does not state is listed too, rather than left out: a kit that looks complete is worse than one that names its gap.

The species

CITES III 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 OK in Thai weather?

This is the cool-climate blue-tongue, so it needs a cooler room than the eastern one. That is the main challenge here.

Can I handle it?

Yes, they are typically calm and slow, and most tolerate handling very well.

How long does it live?

Twenty years or more with good care.

Can I keep two together?

Keep them singly. Adults are territorial and stress each other even without visible fighting.

This sheet states 4 of 7 of the fields this product runs on. What is missing turns something off: enclosure size audit, 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 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.
