Chilean rose tarantula information

The Chilean rose tarantula (Grammostola rosea), also known as the rose hair tarantula, the Chilean fire tarantula, or the Chilean red-haired tarantula (depending on the color morph), is probably the most common species of tarantula available in American and European pet stores today, due to the large number of wild-caught specimens exported cheaply from their native Chile into the pet trade. The species is also known from Bolivia and Argentina.

Chilean rose tarantula Scientific classifications

  • Name: Grammostola rosea
  • Also Known As: Chilean Common, Chilean Fire, Chilean Rose Haired, and Chilean Flame Tarantula
  • Size: Chilean Rose Tarantulas reach a leg span of 4.5 – 5.5 inches.
  • Lifespan (females): 15+ years (males much shorter).


A small (5-10 gallon) tank is suitable for Chilean Rose Tarantulas. The width of the tank should be two to three times wider than the leg span of the spider wide, and only as tall as the spider’s leg span.

2-3 inches of peat moss, soil, or vermiculite can be used as a substrate. Wood, cork bark, or half of a small clay flower pot can be used for a shelter/retreat.

Chilean rose tarantula Life-span

Chilean Rose Tarantulas have not been in the hobby long enough to accurately say how long they live, an educated guess would be 20+ years. Males live significantly shorter lives than females, probably in the region of 3 – 7 years.


Chilean Rose Tarantulas are native to Northern Chile, although they can also be found in Bolivia and Argentina.

Chilean rose tarantula Habitat

An enclosure of approximately 3 times the leg span in length, 2 times the leg span in width and height is required to adequately house this particular spider. They are a terrestrial species and require deeper substrate rather than height to climb. Do make sure that your lid can be securely attached as they will escape given the chance.

The natural habitat of Grammostola rosea is the desert and scrub regions of northern Chile, Bolivia, and Argentina. While previously thought to be wanderers in nature, large numbers have been observed living in burrows in their natural habitat. They generally do not burrow in captivity. They are usually active in the evening or at night.


This tarantula has a diverse diet, including grasshoppers, crickets, moths, beetles, cockroaches, mealworms, small lizards, and mammals. When tarantulas are kept as pets, the best food that can be provided for them are crickets that have been gut loaded on vegetables, as this is the best source of hydrated nutrition for the tarantula.

Feeding Chilean rose tarantula

A live invertebrate prey item of approximately half of the spiders body length is required. You can choose to feed crickets, locusts, mealworms, or even cockroaches. Wingless fruit flies are also a good option for feeding spiderlings.

Approximately 4 or 5 appropriately sized food items should be offered per week, they can be offered all in one go but if they have not been consumed within 24 hours they should be removed and you should try feeding again in a weeks time.


Female spiders benefit from a cooling period of a few months prior to mating. When your mature male makes a sperm web he is ready to be introduced to the female. He should be placed inside the female’s enclosure, at which time he will slowly walk up to the female’s hide vibrating his legs and tapping his feet into the ground to lure the female out.

When she is out far enough the male will usually lunge onto her and push her into an almost upright position so that he has sufficient access to the female’s epigyne. At this time the male will insert one or the other of his pedipalps into the female’s epigyne to inject his sperm.
