The width of the tank should be two to three times wider than the leg span of the spider wide, and only as tall as the spider's leg span. 3 inches of peat moss, soil, or vermiculite can be used as a substrate. Wood, cork bark, or half of a small clay flower pot can be used for a shelter/retreat. Desert blondes will often dig a deep burrow in the substrate.
