Flat rock scorpion

Hadogenes troglodytes

The page we cite does not state this figure. We opened it on 10 Aug 2026 and it gives no temperature for this species at all. The values above may still be right, but we cannot show you where they came from, and nobody here has checked them against a second source. Anything about a sick animal goes to a qualified exotic vet, not to a page. en.wikipedia.org

Drag the sun. Flat rock scorpion is nocturnal, so what it is doing changes with the light.

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.

The numbers

Temperature

152025303540 °C
26–32°Ambient

One ambient band, 26–32°C. This sheet states no warm side, no cool side and no night figure, so none are shown. Same scale on every sheet here, so two species compare by eye.

15–20 cmNose to tail, adult

The size the sheet states for a grown animal.

Why

Two drawings, because they answer two questions. The silhouette is at true scale against a 1.75 m person: it says how big this animal actually is, which no number does for someone who has never seen one. The bar under it is logarithmic and shared by every sheet here, so a 2 cm isopod and a 4 m python both stay readable on the same axis and two species can be compared at a glance.

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 ».

Diet

Feeding rhythm

every 7–14 dAs the sheet states
4Meals in 28 days

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 statesCrickets, roaches · 1 item every 1-2 weeks (very slow metabolism)

Behaviour and handling

HandlingDiscouraged though very docile: low venom, delicate
CommunalCan be kept in pairs/small groups with many crevices
Defense / stress signsWedges deeper into crevice; rarely raises tail

Reproduction

Reproduction
Viviparous; small broods, very slow-growing young on mother's back

Common health problems

Common health issues
SignsDehydration; long lifespan means slow issues
Red flags / quarantine
SignsQT wild-caught (nearly all WC); check hydration

Good to know

  • One of the longest-lived scorpions (25+ yrs) and flattest, for squeezing into rock cracks

What it needs

Enclosure at least 40 × 30 × 25 cmbecause enclosure — 40x30x25 cm with stacked flat rocks/cork
A thermometerbecause temp — 26-32°C
A hygrometerbecause humidity — 40-55% with dry surface

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

Every field this product runs on is stated here. That is not a claim that the values are right: it says what the sheet states, not whether it is true. Whether a human has read it is the badge at the top of this page.

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.
