On the left is the Chilean Rose Tarantula (Grammostola rosea), the most common species of tarantula available in pet stores today due to the large number of exports from Chile into the US pet trade.

It actually originates from the northern Atacama Desert region of Chile, one of the driest deserts on earth. It is a common pet for amateur tarantula enthusiasts because it is low to maintain, attractive, and inexpensive. Females have been known to live as long as 20 years but since there is no substantial study regarding this particular aspect, it is possible that they live longer.

Chilean Roses can be kept in a low-humidity terrarium at least twice its legspan in length, with a retreat for hiding. These spiders are quite happy living at room temperatures of around 20-30°C, and a diet of four to six crickets every 2 weeks. However, its feeding schedule is rather erratic and can fast for weeks to months at a time. Fasting is sometimes an indication of an upcoming moult.

Chilean Roses are usually skittish, running away from danger rather than acting defensively, but they have been known to raise their front legs and show off their fangs in preparation to defend themselves. As with all tarantula from the Americas (New World Tarantula), they have small spine like urticating hairs on their abdomen that they will kick off in response to threats.
