How long must fresh, clean water be available at all times for the Zebra Tarantula?
Answer
At all times
Access to water is considered a non-negotiable requirement for the survival and proper physiological function of the Costa Rican Zebra Tarantula, unlike food intake which can be intermittent. Fresh, clean water must be constantly present within the enclosure. For terrestrial species such as *A. semanni*, this requirement is typically met by providing a shallow water dish. Maintaining water quality is also vital; the water should be changed frequently, usually every few days, to actively prevent stagnation, bacterial proliferation, or contamination arising from shed skin or substrate particles.
