Grammostola pulchra (Brazilian Black Tarantula) MALE 4"

Grammostola pulchra (Brazilian Black Tarantula)

This confirmed 4 inch Brazilian Black Tarantula male has reached his mature size, already showing the deep jet black coloration this species is known for. Males of this species mature at a smaller size than females and grow noticeably faster, so at 4 inches he represents his full, finished form rather than a stage along the way. He makes a striking, ready-to-go display animal on his own, and is also a natural pick for keepers looking to pair him with a mature female. Grammostola pulchra remains one of the calmest, most respected species in the hobby, and this new world tarantula for sale offers that easygoing temperament in confirmed, mature male form.

Why do hobbyists keep Grammostola pulchra?

• Stunning Coloration: Full, solid jet black coloration across the whole body at his mature size.
• Docile Temperament: Calm and slow moving, consistent with the exceptionally easygoing reputation this species holds at every stage and either sex.
• Great Display Species: Known for staying active and visible, frequently rearranging his enclosure and moving objects like water dishes with his fangs.
• Beginner Genus: Grammostola is one of the most trusted beginner genera in the hobby, and pulchra is its most recognized species.

How should Grammostola pulchra be kept?

• Adult Size: Females reach 5 to 6 inches at full leg span, while males mature smaller and faster, with this male at his full 4 inch mature size.
• Enclosure: House this mature male in an 18 by 18 by 12 inch terrestrial enclosure with about 6 inches of substrate and a hide roughly 6 to 12 inches wide. We house males at the same adult tier as females since this is his full, final size.
• Rehousing: This is his forever home. Males mature faster than females and rarely need a further rehouse once they reach this stage.
• Temperature: Maintain between 65 to 75 degrees F with stable conditions.
• Humidity: Keep the substrate lightly moist, letting the top layer dry between mistings. Good ventilation is critical. Cross ventilation works best, but ample top ventilation can also be effective as long as the enclosure is not over-misted.
• Water: A shallow textured water dish works well, something he can grip when climbing out.
• Diet: Prey length runs about a quarter of the leg span, matching the carapace (head). At this size that is about a 1 inch cricket, dubia roach, or superworm. Feed at least once a week.
• Temperament: Calm and slow moving, consistent with the docile reputation this species holds regardless of sex.

Are there any additional notes or considerations?

• Confirmed Male: Sexed male at his mature size, a niche pick for breeding projects or keepers specifically seeking a male, since males have a shorter remaining lifespan after maturity than females.
• Enclosure Rearranging: Frequently rearranges substrate and moves objects, including water dishes, with his fangs, a trait shared across the genus.
• Captive Bred: All Tarantulas are 100% captive bred.

Listing Notes

• This confirmed mature male is fully grown for his sex and ready now, whether the goal is a breeding pairing with a mature female or simply a striking, low maintenance jet black display animal. Males of this species mature faster than females and this one has already reached that point.

Classification Note

There is ongoing discussion within the hobby regarding the distinction between Grammostola pulchra and Grammostola quirogai, as both have appeared in the trade under similar names. While they are recognized as separate species, much of what has historically been sold in the hobby has been labeled as G. pulchra. There is a good chance that, based on descriptions of both species, what we call Grammostola pulchra is actually Grammostola quirogai. These were sold to us as pulchra, so we will continue to use this name until a paper distinguishes hobby pulchra from wild forms of pulchra and quirogai. Since we cannot make species determinations based on color alone, changing the name without that evidence would be irresponsible. That is why we are keeping this listing as Grammostola pulchra "Hobby" form.
