Kenyan sand boas are extremely hardy. They thrive in a tub setup but can successfully be kept in tanks. They do well with a thick layer of particle substrate such as aspen, sani chips, or multiple layers of newspaper. They like it warmer than most snake species with a hot spot of about 90-95 degrees. Ambient humidity is fine, they can be kept pretty dry compared to BPs and most boas. A small water bowel should be provided along with a hide. My kenyan sand boa is a great feeder as are most well established ones I know.
