FoldStack Tube Series-G3 Foldable Ant Nest Four 18mm Test Tubes with Starter Kit and Decorative Landscape Kit

FoldStack Tube Series Foldable Ant Nest with Vertical Stacking System – Modular Expansion Habitat with 4 x 18mm Tubes The FoldStack Tube Series is a premium foldable ant nest system designed for ant keepers who want a clean, expandable, and space-saving setup. Its vertical stacking design allows you to expand upward by adding more modules, creating a scalable multi-level habitat without taking extra desk space. Each module includes 4 large 18mm tubes, and every tube is equipped with an individual chamber blocker, allowing you to open or close tubes separately. This progressive expansion system helps you gradually increase living space as the colony grows, improving brood stability and reducing stress. To enhance comfort and usability, each tube features a gypsum-coated floor that improves grip and makes it easier for ants to walk, carry brood, and transport food. The nest includes a dedicated outworld area for feeding and activity, paired with a tube nest body for organized colony living. Humidity can be customized by adding different water levels to different tubes, or leaving 1–2 tubes dry, creating multiple humidity zones for ants to choose from. This set also includes a starter tool kit and an outworld scenery kit, making it beginner-friendly and ready to use right out of the box.
