Chilean Rose Tarantula Care

Species: Grammostola rosea
Common Names: Chilean Rose Tarantula, Chile Rose Hair, Rose Hair Tarantula

The Chilean Rose Tarantula (Grammostola rosea) is a New World terrestrial species native to the deserts and scrublands of northern Chile and Bolivia. It’s one of the most widely kept tarantulas in the world — often the first species recommended to beginners due to its hardy nature and low maintenance requirements.

While generally calm and slow-moving, G. rosea is also famous for its occasional “mood swings,” displaying a mix of docility and defensiveness. This variability only adds to its charm and makes it an interesting species to observe and keep.

Quick Facts

  • Scientific Name: Grammostola rosea
  • Common Names: Chilean Rose Tarantula, Chile Rose Hair
  • Origin: Northern Chile, Bolivia, and Argentina
  • Adult Size: 12–15 cm (5–6 inches) leg span
  • Lifespan: Females 20–25 years; Males 5–7 years
  • Temperament: Calm but occasionally defensive
  • Experience Level: Beginner

Appearance

G. rosea has a subtle but beautiful color palette:

  • Carapace: Light copper to rose-pink sheen
  • Legs: Gray to brown with pinkish or reddish hairs
  • Abdomen: Dark brown, often with fine copper or red setae

Coloration can vary between individuals — some have a distinct pink hue, while others appear more brown or gray.

Housing & Enclosure

As a terrestrial species, G. rosea thrives in a simple, dry setup with a hide and minimal decoration.

Recommended enclosure sizes:

  • Juveniles: 20 × 20 × 20 cm
  • Adults: 30 × 30 × 30 cm (12 × 12 × 12 inches)

Setup guidelines:

  • Substrate depth: 10–15 cm (4–6 inches) for burrowing
  • Include a hide (cork bark, half log, or burrow starter)
  • Provide a shallow water dish
  • Keep excellent ventilation

This species does best in a dry environment, with humidity provided only through a water dish.

Substrate & Decoration

Recommended substrate:

  • Dry coco fiber, topsoil, or a sand/soil mix
  • Keep completely dry

Decoration ideas:

  • Simple, arid-style layout with rocks, bark, or sparse plants
  • Avoid high humidity or moisture-retaining decor

This is a desert species — damp conditions can lead to stress or health issues.

Temperature & Humidity

  • Temperature: 22–26°C (72–79°F)
  • Humidity: 40–50%

Provide a clean water dish, but do not mist the enclosure. These tarantulas prefer dry air and stable temperatures.

Feeding & Water

Feeding schedule:

  • Slings: Every 5–7 days
  • Juveniles: Every 7–10 days
  • Adults: Every 10–14 days

Diet:

  • Crickets, roaches, mealworms
  • Avoid feeding during pre-molt or fasting periods

It’s normal for G. rosea to fast for weeks or even months, especially as adults — this is not a cause for concern if the abdomen remains full.

Behavior & Temperament

This species is calm and slow-moving but can display sudden defensiveness.

Behavioral notes:

  • Usually docile and tolerant of light disturbance
  • May kick hairs or rear up when annoyed
  • Long fasting periods are common
  • Prefers dry, quiet environments

Each individual has a unique temperament — some are friendly, others a bit feisty!

Handling

G. rosea can be handled, but always cautiously. Some individuals tolerate it well, while others flick hairs or bolt unexpectedly.

Handling tips:

  • Keep handling to a minimum
  • Use slow, steady movements
  • Handle close to a soft surface

Respecting its space will result in a calm and stress-free spider.

Molting

This is a slow-growing species with long intervals between molts, particularly as adults.

Pre-molt signs:

  • Refusal to eat (can last weeks or months)
  • Dull coloration
  • Sealing itself in its hide

After molting, wait 10–14 days before feeding again.

Common Health Issues

G. rosea is exceptionally hardy but can be sensitive to incorrect humidity.

  • Over-humidity: Can cause fungal or mite issues
  • Dehydration: Provide constant access to water
  • Falls: Avoid tall setups

With stable conditions, this species can live for decades.

Breeding (Overview)

G. rosea is occasionally bred in captivity:

  • Pair in cooler months
  • Males court females gently with leg tapping
  • Females lay 200–400 eggs after several weeks
  • Spiderlings grow slowly but are hardy

Many “Chilean Rose” tarantulas in the trade are wild-caught, so captive breeding is encouraged.

Quick Care Checklist

  • Type: Terrestrial burrower
  • Enclosure: 30 × 30 × 30 cm
  • Substrate: Dry soil or coco mix
  • Temperature: 22–26°C
  • Humidity: 40–50%
  • Feeding: Every 10–14 days
