The Brazilian Black tarantula or Grammostola pulchra is a nice-looking spider that owes its name to its velvety, black color. These sturdy spiders are quite docile and reared for their color and look. They are native to some areas of Brazil and Uruguay but are bred in captivity worldwide.
Black tarantulas have a slow growth rate and are in high demand as spiderlings are taken away by breeders who bear them and sell them at high prices.
The Grammostola pulchra can be housed in an enclosure that is not very high as falling from a height can severely injure it or even be fatal. However, ensure that the enclosure is not too narrow as this black Brazilian spider is a terrestrial species and needs more space to move around rather than climb.
You can opt for a terrarium, aquarium, or glass tank. Ensure that the chamber is well-aired at all times; hence an open top with holes on the sides ensures cross ventilation.
How to Prepare Its Habitat
Fill peat, moss, or soil, up to 4 inches thick, at the bottom. A Brazilian black tarantula likes to burrow and digs around most of the time. Ensure that the floor material does not contain any chemicals or fertilizers. Natural cocoa fiber is an excellent substrate that mimics its habitat.
Humidity levels have to be maintained at all times within the enclosure. The recommended temperature is between 60 to 75 degrees F. Uniform humidity can be maintained by placing wet sponges inside the enclosure and misting it once a week.
Misting helps spiderlings, if any, to absorb moisture and remain hydrated always. Make sure there is enough flora inside the enclosure to mimic a natural habitat. Moreover, the Grammostola pulchra likes hiding in places and often disappears from time to time, which is no cause for concern.
What’s the Ideal Temperature?
While in the wild, a Brazilian black tarantula lives in a habitat with temperatures ranging from 65 to 85 degrees F. It is essential to maintain the same temperatures within the enclosure, which can be achieved by fixing heaters below the chamber.
It is crucial to monitor the temperatures constantly, so place a thermometer inside. Leave one area of the enclosure a bit cooler to allow your pet to cool off whenever it feels like it.
Maintaining a proper diet is one of the secrets to rearing a Grammostola pulchra as it is a voracious eater and eats any insect it can overpower. For the young ones, smaller insects like pinhead crickets, tiny locusts, etc., are good.
Adult Brazilian black spiders feed on crickets, mealworms, and roaches. Small lizards and pinky mice are favorites of a Brazilian black spider, though it is not advisable to provide these regularly as they are not suitable for its health.
Molting is a part of the growing process of a Grammostola pulchra, just like any other invertebrate. It is common for your pet to refuse food for days on end while molting, which is, again, no cause for concern. Most Brazilian black spiders tend to become lethargic and go into hiding while molting, and you’ll have to wait until the process gets over naturally patiently.
Summing it Up
A Brazilian black spider is an exotic pet, which is interesting and exciting to rear. The most critical thing to know is its feeding habits and habitat, which decide its longevity. Consulting a vet whenever your pet refuses food for more than a week helps prevent any sudden death of your favorite pet, which is possible even from a fall from a height.
