For substrate topsoil or coco husk/eco earth works well. Their care is similar to tarantulas with the moist substrate, water moisture gradient (dry side and moist side) don't mist (avoid stressing the scorpion), add cover like fake plants and cork bark, deep substrate, shallow water dish (not cotton balls), feeding once a week, and not heating from the bottom (heating is usually unnecessary). For the enclosure a 16 qt tub size works for an adult and deli cups work for smaller babies.
