This is a fossorial spider, so it will require an enclosure which offers more vertical space than floor space. The rule-of-thumb for the height of the enclosure is 3-4x leg span minimum. We recommend this spider be housed in the Spider Haus 'Haplotank'. They will need room to burrow and cross ventilation is not necessary. Fossorial spiders will burrow, and need more depth of substrate. So, fill up the enclosure 2/3 - 3/4 full. Our choice of substrate is a unique blend of coco and other organic materials - Hunter's Premium Substrate. This substrate will retain humidity, allow for sturdy burrows, and resist mold or fungal growth. Offering a cork bark flat can offer cover for the spider until it begins to burrow. Finalize the enclosure by adding Sphagnum Moss, Mixed Leaf Litter, or Magnolia Leaves for aesthetic. Some fossorial spiders build intricate turrets. They will use the organic material available to them to do so.
We anticipate a necessary level of moisture in the substrate for this species. Soak the substrate from the bottom-up by putting the haplotank in standing water. Water will wick up into the substrate from the bottom ventilation, offering the spider a natural bottom-up moisture gradient. Allowing excess water to drain will complete the process. The substrate should never be fully dried out. From others experience, this soaking is only required twice per year.
Common tools which would be helpful in caring for this spider include tweezers. These are used for feeding, cleaning, and rearranging the enclosure if needed. Another useful tool is a Mister. This allows for controlled and purposeful watering.
Our suggestion for feeders is large crickets. Other large insect feeders also work - red runners, dubia roach, mealworms (smash the heads first).
