Indian Ornamental Tarantula Care

Species: Poecilotheria regalis
Common Name: Indian Ornamental Tarantula

The Indian Ornamental Tarantula (Poecilotheria regalis) is one of the most breathtaking Old World arboreal species. Native to the forests of southern India, this spider is renowned for its intricate white and grey patterning, lightning speed, and striking defensive displays.

Though not suitable for beginners, P. regalis is a favorite among experienced enthusiasts due to its elegant appearance, graceful movements, and fascinating natural behaviors. With proper respect and care, this species can thrive and become a stunning showpiece in any advanced collection.

Quick Facts

  • Scientific Name: Poecilotheria regalis
  • Common Name: Indian Ornamental Tarantula
  • Origin: Southern India
  • Adult Size: 15–18 cm (6–7 inches) leg span
  • Lifespan: Females 10–12 years; Males 3–4 years
  • Temperament: Defensive, fast, unpredictable
  • Experience Level: Advanced

Housing & Enclosure

As a strictly arboreal tarantula, P. regalis requires a tall, spacious enclosure with abundant climbing structures. This species naturally inhabits tree trunks and bark crevices, often resting in hollow cavities during the day and emerging at night to hunt.

Recommended enclosure sizes:

  • Juveniles: 20×20×25 cm
  • Adults: 30×30×45 cm (12×12×18 inches) or larger

Provide a vertical setup with:

  • Upright cork bark tubes or slabs (for retreats and anchor points)
  • Dense foliage or artificial plants (for cover and climbing)
  • Cross ventilation (vital for air flow in humid environments)

Ensure the enclosure can be securely closed — Poecilotheria species are extremely fast and can dart out in a split second.

Substrate & Decoration

Although arboreal, P. regalis appreciates some substrate depth for humidity control.

Recommended substrate:

  • 5–8 cm of coco coir, peat moss, or organic topsoil

Decorate with:

  • Vertical cork bark, branches, and plants
  • Leaf litter and moss to create a naturalistic environment

This setup provides both hiding and climbing opportunities, mimicking the layered complexity of its native forests.

Temperature & Humidity

  • Temperature: 25–28°C (77–82°F)
  • Humidity: 70–80%

Maintain humidity through light misting every few days. Avoid overly damp substrate — Poecilotheria prefer a humid atmosphere, not wet soil.

Provide a small, shallow water dish and ensure excellent airflow to prevent stagnant, humid conditions that can lead to mold or respiratory issues.

Feeding & Water

The Indian Ornamental is an aggressive feeder and will readily take live prey such as crickets, roaches, or locusts.

Feeding schedule:

  • Slings: Every 4–5 days
  • Juveniles: Every 7 days
  • Adults: Every 10–12 days

Feed during the evening, when the spider is most active. Remove uneaten prey after 24 hours. Maintain hydration with both a water dish and occasional light misting.

Handling & Temperament

Handling is not recommended. P. regalis is fast, defensive, and capable of delivering a medically significant bite. While rarely aggressive without provocation, it relies on speed and intimidation displays (rearing up and showing fangs) when threatened.

During maintenance or rehousing:

  • Use catch cups, long tongs, and slow movements
  • Never attempt to handle directly
  • Plan all enclosure work carefully before opening

This species should be treated with respect and caution at all times.

Molting

Molting occurs in the spider’s webbed retreat, usually on a vertical surface.

Signs of pre-molt:

  • Dull coloration
  • Refusal of food
  • Increased reclusiveness

Do not disturb during molting. After the molt, wait 7–10 days before offering food to allow the exoskeleton and fangs to harden fully.

Common Health Issues

  • Dehydration: Provide clean water and mist lightly to maintain humidity.
  • Mold or poor ventilation: Ensure strong airflow; avoid over-misting.
  • Stress: Caused by frequent disturbances or lack of hiding spots.
  • Injury: Avoid falls and provide stable climbing structures.

When kept in suitable conditions, P. regalis is robust and long-lived.

Breeding (Overview)

Breeding Poecilotheria regalis is possible but requires care due to the species’ speed and unpredictability.

  • Introduce the male at night with supervision.
  • The female is typically receptive but may become defensive afterward.
  • The female produces an egg sac within 8–12 weeks, containing up to 100–150 spiderlings.

Spiderlings grow quickly and display similar patterning to adults within a few molts.

Quick Care Checklist

  • Type: Arboreal
  • Enclosure: Vertical (30×30×45 cm) with cross ventilation
  • Substrate: Slightly moist coco coir or peat (5–8 cm)
  • Temperature: 25–28°C
  • Humidity: 70–80%
  • Feeding: Crickets or roaches every 7–12 days
  • Handling: Not recommended — defensive and fast

Final Thoughts

The Indian Ornamental Tarantula (Poecilotheria regalis) is a true gem among Old World arboreals — elegant, intelligent, and captivating to watch. Its bold patterns, calm confidence, and lightning reflexes make it a favorite for advanced keepers who appreciate both beauty and challenge.

While this species demands caution and respect, few tarantulas are as rewarding to observe. With proper care, P. regalis will thrive as a striking, graceful representative of the Poecilotheria genus — a classic cornerstone of every serious tarantula collection.
