Description
The Colombian Lesser Black (Xenesthis immanis) Sub Adult Pair is a solid choice for intermediate to advanced keepers looking for a large, impressive tarantula with a manageable temperament. This pair offers the opportunity for future breeding projects or simply to observe the species’ distinct characteristics. We’ve had this product on our shelves since Q1 2025, and customer feedback confirms they consistently receive healthy, well-started specimens.
Stand-Out Features
- Impressive Size Potential: As a member of the “sun tiger” complex, this species is known for its substantial adult size and striking black coloration with subtle patterning.
- Manageable Temperament: While fast and possessing urticating hairs, this species is generally less defensive than some other large terrestrials, making it a compelling display animal.
- Sub-Adult Stage: You’re getting past the most delicate juvenile phase. These spiders are established, feeding well, and on a clear growth trajectory.
- Breeding Potential: Purchasing a pair provides a direct path to captive breeding, contributing to the hobby’s sustainability and reducing demand for wild-caught imports.
- Active & Visible: Expect to see them out and about, especially in the evening. They are not perpetual burrowers, offering good viewing opportunities.

Your Questions Answered
What’s the difference between Xenesthis immanis and other “sun tigers”?
Xenesthis immanis is often considered the “Lesser Black” compared to the more vibrantly colored Xenesthis intermedia. Immanis tends toward a darker, more uniform black base color with less pronounced red or orange on the abdomen, giving it a sleek, powerful appearance.
How do I sex this pair?
We provide a confirmed pair. Sexing in sub-adults is typically done by examining a molt under magnification for spermathecae (female) or by observing the more slender build and longer legs of mature males. Our staff verifies before shipping.
What do you feed them?
We feed ours a staple of gut-loaded crickets and occasional roaches. At the sub-adult stage, they readily accept appropriately sized prey. A consistent feeding schedule of one prey item per spider every 7-10 days is standard.
