Ornithoctoninae sp 'Ho Chi Minh DCF' (Ho Chi Minh Earth Tiger) care guide

availability

Ornithoctoninae sp 'Ho Chi Minh DCF', also known as the Ho Chi Minh Earth Tiger. Please note that Ornithoctoninae is a subfamily, and identification within this group can be complex. 'sp' indicates it's an unconfirmed or undescribed species within that subfamily, and 'Ho Chi Minh DCF' is a locale or trade name. Care is generally similar for most species within this group.

Care Guide: Ornithoctoninae sp 'Ho Chi Minh DCF' (Ho Chi Minh Earth Tiger)

The Ornithoctoninae sp 'Ho Chi Minh DCF', commonly known as the Ho Chi Minh Earth Tiger, is a fascinating but advanced tarantula species from Southeast Asia. Like other members of the Ornithoctoninae subfamily, they are well-known Old World fossorials. This means they are primarily burrowing spiders from the Eastern Hemisphere, characterized by significant speed, a defensive temperament, and potentially potent venom. They are not a beginner species and should be approached with caution and respect.

Quick Facts:

Species: Ornithoctoninae sp 'Ho Chi Minh DCF' (Trade Name/Locale)

Common Name: Ho Chi Minh Earth Tiger

Type: Old World, Fossorial (Burrowing)

Origin: Likely Southeast Asia (Vietnam area)

Adult Size: Approximately 5-6 inches legspan

Lifespan: Females 10+ years, Males significantly shorter (2-4 years after maturing)

Temperament: Defensive, Skittish, Fast. Will readily bite if provoked. Highly secretive.

Urticating Hairs: none

Venom: Medically significant. Can cause intense pain, swelling, and muscle cramping. Seek medical attention if bitten.

Experience Level: Experienced Keepers Only

Enclosure:

Type: As a fossorial species, the most critical aspect is depth for burrowing. Standard terrariums turned on end (with a secure top-opening lid) or purpose-built acrylic fossorial enclosures are ideal. The lid must be secure as they are escape artists.

Size:

Spiderlings (Slings): Small, deep containers like pill vials, film canisters, or 1-2 oz deli cups filled mostly with substrate.

Juveniles/Adults: An enclosure that allows for at least 8-12 inches of substrate depth is necessary. A footprint of 8x8 inches or 10x10 inches is sufficient for an adult, as they don't need much horizontal space, focusing instead on their burrow.

Substrate: A moisture-retentive substrate that holds shape for tunneling is vital. A mix of coco fiber (coco coir), peat moss, and some vermiculite is excellent. Ensure the substrate is packed relatively firmly but not compacted solid.

Decor: Minimal surface decor is needed. A piece of cork bark or similar can be provided as a starter hide to encourage burrowing. Artificial plants are fine but not strictly necessary. Avoid complex setups that make rehousing difficult or dangerous.

Temperature & Humidity:

Temperature: Room temperature is generally fine for this species, ideally between 75-82°F (24-28°C). Avoid temperatures consistently below 70°F or above 85°F. No external heat source is typically needed in an average home environment.

Humidity: Moderate to High. This is crucial for deep burrowers and aids in molting. The goal is to keep the lower layers of the substrate consistently damp, while the surface can be drier.

Method: Instead of misting the entire enclosure, periodically overflow a water dish placed on the surface or strategically pour water directly into a corner of the enclosure to soak the lower substrate layers.

Avoid: Waterlogged or swampy conditions on the surface, as this can lead to mold or mites. The burrow itself will maintain the necessary humidity levels underground. Aim for ambient humidity around 70-80%, but prioritize the substrate condition over a hygrometer reading.

Feeding:

Prey: Crickets, roaches (like Dubia), and appropriately sized mealworms or superworms.

Size: Prey items should be no larger than the tarantula's abdomen.

Frequency:

Slings: 2-3 times per week.

Juveniles: 1-2 times per week.

Adults: Once every 1-2 weeks, or less often depending on the tarantula's abdomen size (a plump abdomen indicates it's well-fed).

Important: Always remove uneaten prey within 24 hours to prevent stress or harm to the tarantula, especially after it has burrowed.

Water:

A shallow water dish should always be available on the surface for juveniles and adults. Ensure it is not too deep.

For slings, a permanently damp corner of the substrate or a tiny bottle cap can serve as a water source.

Temperament & Handling:

The Ho Chi Minh Earth Tiger is a defensive and highly reclusive species. They are incredibly fast and will bolt into their burrows at the slightest disturbance.

If they feel threatened, they are likely to stand their ground, posture defensively, and bite. Their venom is medically significant.

Handling is strongly discouraged and unnecessary. It is stressful for the tarantula and dangerous for the keeper. These are observational pets only. Use long tongs or a catch cup/tub for any enclosure maintenance that requires access.

Molting:

Like all tarantulas, they must molt to grow. Signs include refusing food, becoming lethargic, and potentially darkening in color.

During this time, do not disturb the tarantula. Ensure proper humidity is maintained, as it is critical for a successful molt in fossorial species.

Do not offer food until the fangs have fully hardened after the molt, which can take 7-14 days or longer for adult specimens. Eating too soon can damage their new fangs.

Maintenance:

Spot clean uneaten food or boluses regularly.

A full substrate change is rarely needed and should be avoided if possible, as it destroys their established burrow and causes significant stress. Only perform if absolutely necessary (e.g., mite infestation, persistent mold).

Pros for the Experienced Keeper:

Interesting to observe their burrow-building behavior (when visible).

Can be quite shy and reclusive, appealing to keepers who appreciate secretive species.

Cons:

Rarely seen as they spend most of their time underground.

Extremely fast and defensive.

Potent venom requires careful handling during maintenance/rehousing.

Definitely not a display pet or suitable for handling.

Conclusion:

The Ornithoctoninae sp 'Ho Chi Minh DCF' is a beautiful and impressive tarantula, but its care is suited only for experienced keepers who understand the risks associated with potent venomous Old World species and who appreciate a hands-off, fossorial pet. Providing a deep, secure enclosure with appropriate substrate moisture is key to their well-being. Respect their speed and defensive nature, and you can safely keep this fascinating Earth Tiger.
