Discover the impressive yet lesser-known Dark Blue Sky Rocks, perfect for creating natural aquarium setups. These smooth, dark blue stones with brown grain resemble river pebbles and are ideal for layouts that mimic the original habitats of aquarium animals, such as river landscapes or terraces. The flat shape of the rocks makes them easy to install and provides a great environment for microorganisms, which help maintain optimal water values. Shrimps particularly enjoy feeding on the biofilm that forms on the stones. With a low calcareous content, they are perfect for soft water aquariums and aquascaping. Combining them with green aquatic plants creates a beautiful and natural look, especially when paired with a light-colored substrate or roots.
