Setup

The numbers

Thermal gradient

152025303540 °C
24–29°Cool side
32°Warm side

A real gradient, 32°C warm against 24–29°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 24-29 °C

Enclosure
A 20-gallon tank is suitable for one green snake, but larger is always better

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

A heat sourcebecause Temperature — warm 32 °C / cool 24-29 °C
A thermostat to regulate itbecause Temperature — warm 32 °C / cool 24-29 °C
A thermometerbecause Temperature — warm 32 °C / cool 24-29 °C
A hygrometerbecause Humidity — 50-70 %
UVB, stated as beneficial rather than requiredbecause UVB — UVB lighting is recommended to support their overall health; provide a 12-hour light-dark cycle using a UVB bulb
Not stated: The size of the enclosurethis sheet describes the enclosure without a figure: « A 20-gallon tank is suitable for one green snake, but larger is always better »

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.

Food

Diet

Feeding rhythm

every 2–3 dAs an adult
14Meals in 28 days

Twenty-eight days, one row. Each band is a meal window. The sheet gives several ages on one line; this is the adult figure.

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 stateslive or freshly killed insects, such as crickets, grasshoppers, and caterpillars; feed juveniles every 2-3 days and adults every 3-5 days

The species

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?

Insects only, mainly crickets and soft worms. It does not take rodents at all.

Is it difficult?

Yes for Thailand. It is a cool-climate species, it ships badly and it is delicate. Not a beginner snake.

How big does it get?

Small, around 40 to 60 centimetres and pencil-thin.

Can I handle it?

Really not. It is a look-only snake and handling is the fastest way to lose one.

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.
