Malaysian Forest Scorpion

Malaysian Forest Scorpion key facts

Care level

Intermediate

Lifespan

6-8 years

Size

10-20cm total length (guideline for the genus Heterometrus)

Temperature

Humidity

80%

Diet

Live insects such as crickets

Temperature & Humidity

Create a gradient with a warm end around 30 C and the other end at room temperature. Aim for 80% or more humidity by limiting ventilation and misting daily.

Enclosure

Use deep coco fibre or peat with a cork hide per animal and a shallow water dish they cannot drown in. Fix the heat mat to the side.

Diet & Feeding

Offer live prey such as crickets once a week, one or two per scorpion, and remove any that are still uneaten the next day.

Temperament & Venom

Venom across the genus is weak and no human deaths are known. Most animals are docile, but aggressive individuals do occur.

Notes

It is hard to tell from congeners and often traded under other names. Care is essentially the same across the genus, so an uncertain name does not change husbandry.

About Malaysian Forest Scorpion

A large jet-black scorpion from the Indochina Peninsula, easily confused with close relatives and sometimes sold under other names. An intermediate-level exotic pet — here's what to know before bringing one home.

7 things to know before welcoming a Malaysian Forest Scorpion

1. 1High Humidity & Hiding Spots

   As a species from tropical rainforest habitats, its enclosure needs consistently high humidity. Use a deep layer of moisture-retentive substrate and add hides or driftwood, since this species stays tucked away during the day and becomes active at night.

2. 2Handle With Caution

   This is a large scorpion with well-developed pincers and a stinger, and it isn't especially calm-tempered. It's best kept as a display animal in a well-designed enclosure rather than one you handle directly.

3. 3Understand the Sting Risk

   Like all scorpions, it carries venom, but how risky a sting actually is varies by individual and by the person's own sensitivity. Rather than relying on any blanket claim, it's safest to avoid handling it bare-handed and take basic precautions.

4. 4Grows Into a Large Adult

   As a rough guide for the genus Heterometrus, adults can reach roughly 10–20 cm in total length, giving it real presence among pet scorpions. Plan for an enclosure with room to grow as it matures.

5. 5Carnivorous Feeder

   It's a carnivore that mainly eats insects such as crickets. Digestion is slow, so frequent feeding isn't necessary, and any uneaten prey should be removed promptly to prevent mold or pests.

6. 6Easily Confused With Relatives

   Despite the trade name "Malaysian," most records actually come from Vietnam, Cambodia, and Thailand, so the name doesn't necessarily match the animal's true origin. It closely resembles related species and is sometimes sold under other names, so it's worth checking listing details carefully.

7. 7Choose an Escape-Proof Setup

   This species is strong enough to try pushing through small gaps in a lid, so a tightly sealing enclosure or one with a secure locking mechanism is recommended. Setting up the enclosure, substrate, and hides in advance makes the introduction smoother.
