Using Rock Black Lava in the aquarium creates a natural and unusual look. The dark stones form a beautiful contrast to the plants and fish in the aquarium, making their colours stand out even more intensely. They also serve as a hiding place and refuge for shy or territorial fish. This reduces stress and thus contributes to the long-term healthy and species-appropriate keeping of the animals. Lava stone also offers a functional advantage. The porous structure of the rock allows the colonisation of filter bacteria, which ensure the biological breakdown of harmful substances in the water.
