The Brazilian spiders need a good and clean terrarium for living. They usually need an enclosure that is nearly three times the span of their legs. These spiders are terrestrial organisms.

If their enclosure is made too high, they may fall and break their legs. When they are kept in captivity, it is imperative that you provide them with an arid and fresh environment.

Also, these tarantulas are native to the grasslands in Brazil and Uruguay and therefore have a body type that thrives well in the breezy environment.

So, it is important that you study well the requirements for your pet Brazilian spider.

Every species need space to grow and thrive. If you are keeping spiders in captivity, then you must be ready to take some extra care of them.

The Brazilian spiders can grow in full size to nearly a length of eight inches. These spiders, thus, need an area of 3 inches around their bodies, for easy movements.

Spider pet parents must also ensure that they do not build very high tank enclosures such that their spider may fall down. Falling down from heights can directly result in the breaking of spider legs or even death in some cases.

Their tanks should be cleaned regularly and any insects given to them for food should be removed from the tank within 24 hours.

Therefore, it makes it difficult to track down their growth rate throughout the years. 


If you think that all Brazilian tarantulas have a uniform lifespan irrespective of their gender, then you may be wrong. The male black tarantulas’ average lifespan is around 6 to 8 years.
