Sri Lankan Banded Ornamental Tarantula Care

Species: Poecilotheria fasciata
Common Name: Sri Lankan Banded Ornamental Tarantula

The Sri Lankan Banded Ornamental Tarantula (Poecilotheria fasciata) is a striking Old World arboreal tarantula known for its bold leg banding, vivid contrasts of yellow, grey, and white, and lightning-fast movements. Native to the forests of Sri Lanka, this species is a quintessential example of the elegance and power found in the Poecilotheria genus.

Although highly defensive and best suited to experienced keepers, P. fasciata is a rewarding display species that exhibits intelligence, fascinating hunting behavior, and intricate webbing habits when given the right environment.

Quick Facts

  • Scientific Name: Poecilotheria fasciata
  • Common Name: Sri Lankan Banded Ornamental Tarantula
  • Origin: Sri Lanka
  • Adult Size: 18–20 cm (7–8 inches) leg span
  • Lifespan: Females 12–15 years; Males 3–4 years
  • Temperament: Fast, defensive, nervous
  • Experience Level: Advanced

Housing & Enclosure

Like all Poecilotheria, P. fasciata is a strictly arboreal species that thrives in tall, well-ventilated enclosures. In the wild, it resides in tree hollows and bark crevices, constructing silken retreats high above the forest floor.

Recommended enclosure sizes:

  • Juveniles: 20×20×25 cm
  • Adults: 30×30×45–50 cm (12×12×18–20 inches)

Setup tips:

  • Upright cork bark tubes or slabs as primary retreats
  • Artificial or live foliage for cover and web anchoring
  • Strong cross ventilation for air flow
  • Secure lid — Poecilotheria are fast escape artists

These arboreals require vertical climbing space and dense structure for security. A naturalistic setup enhances their behavior and overall wellbeing.

Substrate & Decoration

A thin, moisture-retaining substrate layer will help balance humidity.

Recommended substrate:

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

Decorate with:

  • Vertical cork bark or logs
  • Branches, vines, and plants for climbing and web support
  • Moss or leaf litter to maintain microclimate stability

Natural textures and hiding options promote a healthy, active tarantula that displays natural postures and behavior.

Temperature & Humidity

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

Light misting every few days helps maintain humidity. Allow partial drying between sprays to prevent mold.

Ensure cross ventilation — Poecilotheria need humid air, not damp enclosures. Provide a small water dish and monitor for consistent cleanliness.

Feeding & Water

The Sri Lankan Banded Ornamental is a voracious feeder with lightning reflexes. It prefers to ambush prey from within its web retreat.

Feeding schedule:

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

Feed crickets, roaches, or locusts of appropriate size. Remove uneaten food after 24 hours to avoid stress.

Maintain a fresh water dish and mist lightly to create drinking droplets on webbing.

Handling & Temperament

Handling is strongly discouraged. P. fasciata is one of the more defensive and reactive Poecilotheria species, capable of moving with incredible speed. Its venom is medically significant, with reported bites causing severe pain, muscle cramps, and systemic symptoms.

For any enclosure maintenance:

  • Use catch cups and long tongs
  • Move slowly and plan ahead
  • Never corner or provoke the spider

Respect its space and you’ll rarely encounter defensive behavior — but never underestimate its speed or reach.

Molting

Molting occurs inside the spider’s silk retreat, usually vertically aligned.

Pre-molt indicators:

  • Faded coloration
  • Food refusal
  • Increased hiding behavior

Do not disturb during this time. After molting, wait 7–10 days before offering food to allow proper hardening of the exoskeleton and fangs.

Common Health Issues

  • Poor ventilation: Leading to mold or respiratory problems
  • Over-humidity: Stressful — maintain balance with airflow
  • Dehydration: Ensure regular misting and a clean water source
  • Stress or injury: Caused by excessive handling or enclosure changes

When stable, P. fasciata is hardy and thrives with minimal interference.

Breeding (Overview)

Breeding P. fasciata is achievable but should be attempted only by experienced keepers.

  • Introduce the male to a well-fed female at night
  • Mating is often fast and uneventful, but supervision is essential
  • The female may produce an egg sac within 8–10 weeks containing 100–150 spiderlings

Spiderlings are hardy and fast-growing, showing early signs of their adult patterning.

Quick Care Checklist

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

Final Thoughts

The Sri Lankan Banded Ornamental Tarantula (Poecilotheria fasciata) captures the essence of the Old World arboreal experience — stunning, intelligent, and unapologetically bold.

Its striking banded pattern, graceful climbing, and commanding presence make it a standout in any serious collection. While best left unhandled, P. fasciata offers endless fascination for those who appreciate natural behavior and beauty from a safe distance.

Elegant yet intense, P. fasciata is a true Poecilotheria classic — a symbol of why this genus is so beloved among advanced tarantula keepers.
