A live culture of 200 or more Sinella curviseta springtails. They are larger and slower than Folsomia candida, so they are easier to see as they move through a build.
Like the Folsomia culture, they are captive bred. They suit keepers who prefer a larger, slower springtail. Open the tub over the build only when you are ready to add them, and keep it stable until then. Their slower pace makes them easy to observe as they move around the build.
