Chilean Rose Tarantula Care
Species: Grammostola rosea
Common Name: Chilean Rose Tarantula / Chile Rose Hair Tarantula
The Chilean Rose Tarantula (Grammostola rosea) is one of the most common and recommended tarantulas for beginner keepers. Known for its calm temperament, easy care requirements, and long lifespan, this hardy species makes an excellent introduction to tarantula keeping.
Native to the dry scrublands and deserts of northern Chile and parts of Bolivia and Argentina, the Chilean Rose thrives in low-humidity, semi-arid conditions — making it one of the few tarantulas that prefers things on the drier side.

Housing & Enclosure
The Chilean Rose is a terrestrial species that enjoys having floor space and a secure, dry environment. A large enclosure is not necessary — this tarantula appreciates a simple setup.
Recommended enclosure sizes:
- Juveniles: 10–15 cm tub or small terrarium
- Adults: 30×30×30 cm or similar-sized enclosure
Provide a hide (such as cork bark or a half coconut shell) and about 8–10 cm of dry substrate. They rarely burrow deeply, but some individuals will dig slightly beneath their hide.
Avoid excessive height in the enclosure — a short fall can injure them. A tight-fitting lid with ventilation holes is essential for safety and airflow.
Substrate & Decoration
Use a dry substrate such as coconut fiber (coco coir), peat moss, or topsoil — kept mostly dry with only occasional light misting on one corner if necessary.
Decorate minimally: a hide, a water dish, and maybe a few fake plants or rocks for aesthetics. This species doesn’t need humidity-heavy decor and prefers a clean, uncluttered environment.
Temperature & Humidity
- Temperature: 22–26°C (72–79°F)
- Humidity: 55–65% (dry conditions preferred)
The Chilean Rose is tolerant of room temperatures, so no heating is usually required unless your home gets cold. Good ventilation is crucial — excessive moisture can stress or even harm them.
Keep a shallow water dish available at all times for drinking.
Feeding & Water
The Chilean Rose Tarantula is famous for its slow metabolism and unpredictable feeding habits. It can go weeks or even months without eating, especially adults. This is normal and not a cause for concern if the spider looks healthy.
Feeding schedule:
- Slings/Juveniles: Every 5–7 days
- Sub-adults: Every 7–10 days
- Adults: Every 10–14 days (or less if fasting)
Feed crickets, mealworms, roaches, or similar-sized prey. Remove uneaten insects within 24–48 hours. Provide clean, fresh water in a small dish at all times.
Handling & Temperament
The Chilean Rose is often calm and slow-moving, and many individuals tolerate gentle handling. However, behavior can vary — some are defensive or skittish.
When handling, always be gentle and low to the ground to prevent injury if the tarantula falls. Use a catch cup if the spider seems nervous or defensive.
Tip: Never handle a tarantula immediately after a molt — the exoskeleton is soft and fragile.
Molting
Molting is an essential process of growth and renewal. Signs that your Chilean Rose may be preparing to molt include:
- Refusal to eat
- Dull, darkened coloration
- Resting on its back or side (a normal molting position)
Do not disturb or feed the spider during this period. Wait at least a week after the molt before offering food again. Always remove the old exoskeleton once the tarantula has hardened.
Common Health Issues
- Dehydration: Provide constant access to clean water. Signs include shriveled abdomen or lethargy.
- Mold or Fungus: Too much moisture — increase ventilation and keep the substrate dry.
- Stress: Overhandling, bright light, or excessive humidity can cause pacing or climbing behavior.
- Injury: Avoid falls or sharp objects inside the enclosure.
Breeding (Overview)
Breeding Grammostola rosea is relatively straightforward, but patience is required. Females are long-lived and may not always be receptive.
- Introduce the male carefully after both have been well-fed.
- Mating often occurs calmly, but supervise in case the female becomes aggressive.
- Females may lay an egg sac several months later, containing 100–300 spiderlings.
Raising slings is simple — they can be kept communally for a short time before separating.
