Small, low-maintenance, and simply beautiful: With the NanoCubes, miniature aquatic worlds can be created that allow for optimal coexistence of invertebrates and plants in minimal amounts of water, all with as little maintenance as possible. The aquariums feature a special depth effect thanks to the panoramic glass with curved front corners. Included in the package are the cover glass, a thermometer, background film, and a safety mat made of foam rubber. Perfect for beginners.
