Hybrid Nest Stand Type I Wide This nest is for large ants such as *Pachycondyla chinensis*. It's a stand-up type, making observation easy. The design is based on the tunnels of a real ant nest. You can raise ants while imagining how they live in the soil. - There is a test tube for water supply on the back of the nest, so you can check the water supply status. - There are connection holes on the left and right, so you can connect nests and feeding areas. You can enlarge the nest as needed. - The connection holes are screw-type, so they won't come off easily, allowing for safe keeping and movement. - The top two corners of the glass surface are magnetic, and the bottom is inserted into the nest, so there is no worry of it coming off. - It comes with a stable stand, allowing you to view it from the side. You can observe from the ant's perspective. - The stand uses magnets and is easy to remove. - It can be used not only for large ants but also for small ants. Suitable for small to medium-sized ants found anywhere in Japan, as well as most of the overseas ants we handle. Easy to observe and easy to raise, making it ideal for children's science projects.
