Indian ornamental tarantula

A stunning, fast, arboreal Old World tarantula from India with intricate fractal patterning and potent, medically significant venom. Beautiful to observe but strictly a look-don't-touch species for experienced keepers only.

Part of the Tarantulas

Theraphosid spiders kept as low-maintenance display invertebrates. New World species are generally docile with mild venom but bear irritating urticating hairs, while Old World species lack those hairs but tend to be fast, defensive, and have more potent (though rarely life-threatening) venom.

Habitat & space requirements

From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum

Juvenile / sub-adult arboreal

8 × 8 × 12 in (juvi) → 10 × 10 × 14 in (sub-adult)

Tall enclosure with vertical cork-bark slabs reaching most of the height, cross-ventilation, 2–3 in of substrate, and a water dish. Arboreals web a tube-retreat against the bark rather than burrow. Indian ornamentals (Poecilotheria regalis) are large fast old-world arboreals — same Poecilotheria caveats: medically significant venom, expert keepers only.

Recommended

Adult arboreal vivarium

12 × 12 × 18 in, vertical

Vertical footprint with multiple cork verticals, plants or fake foliage for cover, and front-opening access. Humidity is maintained via substrate moisture and a deep water dish, not by sealing off airflow.

Ideal

Planted arboreal bioactive

12 × 12 × 24 in+, bioactive planted

Tall bioactive vivarium with live plants, dense cork-bark verticals, leaf litter, and a springtail/isopod cleanup crew. Cross-ventilation panels at top and bottom prevent stagnant air, which arboreals are intolerant of.

Life & growth stages

How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg

These invertebrates lay eggs — often in a guarded clutch, a silk sac (spiders), or a brood (carried by female isopods). The eggs are small and soft and develop without a true larval or pupal transformation.

Photo coming soon
Juvenile

Juveniles hatch as miniature versions of the adult and grow by molting their exoskeleton (or, in snails, by enlarging the shell). They gain size, segments, or leg pairs and gradually take on adult coloration with each molt.

Adult stage
Adult

Adults reach full size and reproductive maturity with the species' mature form and coloration. Many arachnids and myriapods continue to molt as adults, and sexes can differ in size or in specialized appendages.

Habitat & enclosure

Arboreal: provide a tall enclosure, roughly 30 x 30 x 40 cm (taller than wide) for an adult, with secure, escape-proof ventilation. Furnish with one or more vertical cork bark tubes/slabs fixed firmly so the spider can build silk retreats against them. Maintain 24-28 C (75-82 F) and moderate humidity (65-75%); provide cross-ventilation to prevent stagnant, mold-prone air. A shallow water dish gives drinking water and ambient humidity. No UVB needed.

Substrate

Use a few inches of moist-but-not-wet coco fiber/peat substrate at the base for humidity buffering and in case of falls, but the spider lives vertically. Keep one corner lightly damp; let the surface dry between mistings to avoid mold.

Equipment & setup

Tall, front- or top-opening glass/acrylic enclosure with locking, escape-proof lid and ample cross-ventilation. Vertical cork bark tube, shallow water dish, and a fine hygrometer/thermometer. Supplemental heat (room ambient or a low-watt heat source on a thermostat, away from the enclosure wall) only if the room is cool. A long pair of forceps and a deli/catch cup are essential safety tools.

Diet

Insectivore. Feed appropriately sized live feeders: crickets, dubia roaches, locusts. Slings every 4-5 days, juveniles/adults roughly once a week, offering prey no larger than the spider's body. Remove uneaten prey within 24 hours, especially around molts when the spider should not be fed.

Behavior & temperament

An Old World species with no urticating hairs; its primary defenses are speed, a threat display, and a defensive bite delivering potent venom. P. regalis bites can cause intense pain, severe muscle cramping that can persist for days, and systemic effects — medically significant and well documented in the literature, though no fatalities have been recorded and there is no specific antivenom. Extremely fast and prone to bolting. Not handleable and not suitable for beginners. Observe only; use slow, deliberate husbandry with a catch cup on hand.

Health

Hardy if kept dry-but-ventilated; the main killers are falls (fatal abdomen ruptures from height) and poor ventilation causing fungal issues. Watch for dehydration (shriveled abdomen) — keep the water dish full. Never handle: bite envenomation is the chief safety risk to the keeper. Fast for 1-2 weeks pre-molt; do not disturb a molting spider.

Tips, DIY & hacks

Treat every rehouse as a controlled operation: work over a large bin, keep a catch cup ready, and never put a hand inside. Anchor cork bark so it can't shift and trap or injure the spider. Because of potent venom, keep contact info for a poison control center handy. Confirm legality before acquiring — the entire genus Poecilotheria has been listed on CITES Appendix II since 2019, so international trade requires permits and some jurisdictions add further restrictions.
