Brazilian Black Tarantula Information

A must-have for any tarantula collection, and a black beauty among all tarantulas. The Brazilian Black (Grammostola pulchra) is well-known for being one of the most docile tarantulas; it has a very docile temperament, being only nervous as young but maturing into gentle giants.

Brazilian black tarantulas are medium-sized and stout, with the ability to reach up to 8 inches when fully grown, though somewhere between 6 to 7 inches is common. The females in this species can live upwards of 20 years, while the males have a shorter lifespan with an average between 6 and 8 years.

Brazilian Black is not afraid to be seen and makes an excellent exhibition tarantula, especially with its unusual and breathtakingly stunning satin-black color, especially after molting. It’s always difficult to find and usually expensive, but it’s always worth it.

Care Requirement

Any tarantula’s enclosure should ideally be 2-3 times its leg spread. Because Brazilian black tarantulas are terrestrial in nature, length and width are significantly more significant than height. Falls from a cage that is too high might injure or kill your Brazilian black.

Terrariums, aquariums, or plastic/acrylic cages are ideal, but keep your tarantula’s abode adequately aired. Cross ventilation is more significant than top ventilation. This can be accomplished by drilling holes in the enclosure’s sidewalls. It is critical to provide hiding places for your tarantula. To create hiding spots, some keepers adorn their cages with artificial flora and bits of wood or cork bark.



The Brazilian black tarantula dwells in an environment with temperatures ranging from 65 to 85 degrees Fahrenheit in the wild. Ideally, your tarantula should be kept at a temperature of 75 to 85 degrees Fahrenheit; nevertheless, many keepers have discovered that their tarantulas perform well at room temperature.

If you keep your home too cool and feel the need to add a heat source, a heat mat on the enclosure’s side or bottom would suffice. However, use a thermostat to properly control the temps and always leave a cool side for your tarantula to escape to if necessary.


The Brazilian black tarantula is an opportunistic burrower, meaning it will dig if provided enough substrate. However, the recommended minimum depth for your Brazilian black is 4 inches of bedding. A good substrate is chemical-free potting soil or ground coco fiber.

This species’ humidity levels are fairly low in contrast to others, although allowing for a range of 60 to 75 percent is adequate. This can be accomplished by including a water bowl in the terrarium. Misting the enclosure’s side allows your spiderlings to sip and stay hydrated. It is rarely required for adults.


Food and Water

Tarantulas are hunters that require live prey to survive. Adults can eat crickets and other large insects that are pesticide-free. Adult tarantulas eat once or twice a week, whereas juvenile spiders can be fed more frequently. While these tarantulas can consume a large number of insects, they may also go for extended periods without feeding.

Feeding them appropriately also entails maintaining pet crickets beside your spider and feeding them a diet that maximize your pet’s nutrient intake. Some keepers propose feeding a full-grown spider a pinky mouse every now and again, although the calcium in the mammal’s bones may outweigh the spider’s dietary requirements. As a result, supplementing with this food source in captivity is not advised.

Provide a flat ceramic pan of clean, clear, and chlorine-free water; deeper dishes provide a drowning hazard to tarantulas. However, when refreshing it, take care not to spill anything, as this species will become stressed if their tank substrate becomes wet.
