The Chilean Rose: A Guide to the Grammostola rosea (Red Colour Form)
Introduction
For many long term enthusiasts, the Grammostola rosea, or the Chilean Rose, was the spider that started it all. While the standard "grey" form is common, the Red Colour Form (RCF) is a stunning elevation of this hobby classic. Hailing from the arid scrublands of Chile, this species is draped in a beautiful, burnt-orange to copper-red coat of setae that shimmers under enclosure lighting. It isn't just a spider; it is a piece of hobby history. For the tarantula keeper, the RCF offers a perfect mix of rugged hardiness, a manageable temperament, and a vibrant, "autumnal" aesthetic that looks fantastic in a naturalistic setup.
Size, Growth, and Longevity
The Grammostola rosea is a medium-sized terrestrial tarantula, typically reaching an adult leg span of 12cm to 14cm. One thing every enthusiast should know is that this species defines the word "patient." They have a notoriously slow growth rate, often taking several years to reach maturity. However, this slow pace is the secret to their incredible longevity. Females are legendary for their lifespan, often living for 20 to 25 years, making them a true lifelong companion. If you are looking for a spider that will grow with you over decades, the Chilean Rose is the gold standard.
Temperament and Suitability
The Rosea is widely regarded as one of the most docile and calm species available. As a new world tarantula, it is generally slow moving and predictable. While they do possess urticating hairs, they are far more likely to simply sit still or slowly wander than to flick hairs or act defensively.
Because of this gentle nature, it is the ultimate beginner species. It is a "low-stress" spider that is perfect for those who are still gaining confidence in arachnid care. One quirk to note: G. rosea is famous for "fasting"—they may occasionally go several months without eating for no apparent reason. Don't panic! As long as the spider is hydrated and has a plump abdomen, this is just part of their unique Chilean charm.
Simplified Care
The Chilean Rose is a hardy terrestrial inhabitant that thrives in a straightforward environment. They require a setup that prioritizes floor space with a relatively dry substrate. Because they come from arid regions, they do not tolerate "swampy" or high-humidity conditions well. A simple mix of dry coco-fibre or topsoil with a shallow water dish is all they need.
To keep them comfortable in a home, aim for temperatures between 18C and 25C. They are opportunistic burrowers, so providing 8–10cm of substrate and a sturdy cork bark hide will allow them to create a secure home. They are very easy to feed, accepting crickets, locusts, or roaches with ease (when they aren't on one of their famous hunger strikes!). Their low-maintenance needs make them an ideal choice for a busy keeper.
Conclusion
The Grammostola rosea is a timeless masterpiece of the tarantula world. Its stunning copper-red hues, legendary hardiness, and gentle personality make it a cornerstone of the hobby. Whether you are buying your very first spider or adding a vibrant classic to an established collection, the Red Chilean Rose is a rewarding, long-lived treasure that truly stands the test of time.
