Brazilian Black Tarantula Care Guide

The Species: Brazilian Black Tarantulas (Grammostola pulchra) are a common species of Tarantula to be kept as pets and are considered to be one of the best beginner species due to their docile nature and calm disposition. As the name would suggest it, this species is native to Brazil but also to Uruguay and inhabits grasslands. A more arid species compared to other Tarantula species. All Tarantula species are solitary as are very territorial and aggressive towards one another, even putting them together for breeding can result in the females killing the male.

Enclosure: This species is terrestrial and should be housed in plastic rub with good ventilations such as a faunarium or in a glass terrarium. As adults, these animals should be kept in an ideal enclosure size of 30x30x30cm however as slings (babies) or juveniles, they should be provided with appropriate sized enclosures not too large as to stress them out.


Being a species residing within arid grasslands they need suitable substrate made from a soil based substrate, we would recommend Arcadia Earth Mix however other substrates are also appropriate ProRep Spider or ProRep Bio Life Forest, we wouldn't generally using arid substrates such as sand or arid soils. They should be provided with a deep layer of substrate to give them the option to create a burrow within the substrate.

Various decor and apparatus should be included to provide as natural of an enclosure as possible. Woods, rocks, caves and foliage are all suitable to use for this species along with a very small bowl for water should be readily available as well.

Heating: These animals should be kept at a temperature range of 18-29 degrees celcius (65-85 degrees farenheight). They should be provided with a hot and cool end and with a basking spot to reach peak temperatures. Heating should be provided by a nano heat lamp or a heat mat on a thermostat, all heating should be on a 12 hour cycle, turning off at night to provide a natural drop in temperature.

Lighting: Tarantulas don't require lighting such as UVB but providing them with a day/night sequence can help improve their wellbeing. This can be accomplished using UVB or LED lighting, red lighting can also make spiders more active so you can observe their behaviours more. All lighting should be on a 12 hour cycle.



Humidity: Being a species residing within arid grasslands, Brazilian Black Tarantulas should have levels of humidity of approximately 55-65% and should ideally not raise above that. When in moult, it is best to keep the humidity higher, closer to 65%. These humidity levels can be reached by spraying the enclosure daily with water but it should be kept in mind to not spray the animal directly as to not allow mould spores to grow on them.

Diet: Tarantulas are natural predators which actively hunt their prey. This means that they have to be given live food. They can be given a wide variety of insects for food starting with fruit flies for spiderlings (babies) and going up to a wider range including crickets, locust, cockroaches, morio worms etc. They should be given appropriate sized feeds dependant on the size of the Tarantula themselves, they should be fed every 2-3 days and at a minimum once a week. If there is still food in the enclosure from their previous feed, don't add more and if they are going into mould or have just finished it, they should be given a few days before feeding.


Water is also an extremely important aspect to an animals diet and constant water access should be provided in a water bowl and should be changed daily, we generally recommend RO water or mineral water due to tap water containing chlorine which can be harmful to some animals.
