Grammostola grossa (Guarani Giant Tarantula)

Grammostola grossa (Guarani Giant Tarantula)

Grammostola grossa is a rare South American species often compared to the famous Brazilian Black, but with its own distinct look and a size to match its name. Adults settle into a deep, almost black coloration dusted with a fine silver hue throughout, while spiderlings hatch out unusually large, nearly an inch in leg span, leggy and covered in a soft fuzzy coat. Grab this rare docile new world tarantula for sale before it's gone, since it doesn't stick around often.

Why do hobbyists keep Grammostola grossa?

• Stunning Coloration: A deep, almost black body dusted with fine silver hairs gives adults a frosted look that stands apart from other dark Grammostola species.
• Fluffy Appearance: Both slings and adults carry a noticeably fuzzy coat, giving this species a softer, less intimidating look than most Grammostola.
• Large Size: One of the larger Grammostola species in the hobby, reaching around 7 inches at full leg span.
• Docile Temperament: Calm and easygoing, an enjoyable species to keep on display.
• Rare in the Hobby: Not often available and quick to sell out when it is.

How should Grammostola grossa be kept?

• Adult Size: Reaches around 7 inches at full leg span, one of the larger Grammostola species in the hobby.
• Enclosure: Provide roughly 3 to 4 times the leg span as footprint, 2 times the leg span as height, with substrate at least 1 times the leg span deep and a hide 1 to 2 times the leg span wide. For a one-inch sling, that means starting around 3 to 4 by 3 to 4 by 2 inches, sizing up as it grows.
• Temperature: Keep between 65 to 75 degrees F.
• Humidity: Keep the soil from drying out completely. 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 water dish is strongly recommended. This species is moisture-dependent, especially during molting.
• Diet: Crickets, roaches, and similar feeders sized to the carapace (head). A fast grower, especially given the head start slings get from hatching out so large.
• Temperament: Docile and calm, more laid back than many large South American terrestrials of similar size.

Are there any additional notes or considerations?

• Sling Growth: Hatches out nearly an inch in leg span already, leggy and fast growing from day one, with a soft fuzzy coat that carries into adulthood.
• Frosted Look: Adults hold a deep, almost black coloration dusted with fine silver hairs for a smoky, frosted finish, similar in tone to the Brazilian Black but with its own distinct texture.
• Captive Bred: All Tarantulas are 100% captive bred.
