Darwin Black Lava Stone is a unique and visually appealing volcanic rock that is ideal for aquariums and terrariums. This porous rock is rich in minerals and has a rough texture that makes it perfect for creating natural and aesthetically pleasing aquatic landscapes.

The dark colouring of the rock, which is a combination of black and dark grey tones, provides a fascinating contrast to the lighter colours of the aquatic plants, mosses and fauna in the aquarium or terrarium. The porous surface of the black Darwin lava stone is ideal for beneficial bacteria and microorganisms to grow and thrive. This makes it an excellent option for creating a bioactive environment in aquariums, terrariums and vivariums, which is essential for maintaining healthy ecosystems.

The rough texture of Darwin black lava stone also provides the ideal surface for epiphytic plants such as anubias and mosses such as java moss, creating a natural-looking landscape that mimics the natural environment of many aquatic and terrestrial organisms. It can also absorb and release water quickly due to its porous nature, making it an excellent choice for planted pools, humid habitats and those that require high humidity.

This inert stone does not harden the water and is therefore ideal for sensitive aquatic animals and plants.


  • Deep black lava rock with fine texture and cracks
  • Provides a striking contrast to plants in aquariums
  • The highly porous texture provides excellent support for mosses and perching plants
  • Complements wood very well for the Ryoboku style and for terrariums
  • Does not harden the water and is therefore ideal for sensitive aquatic animals and plants


These Rocks sets are untreated natural products. They can be used in aquariums as well as in terrariums. It is recommended to clean and rinse Rocks decoration under running water before using it in the aquarium. This removes the finest stagnant particles, which can otherwise cause cloudiness when a new aquarium is set up. Slight residues of moss or lichen cannot be ruled out completely.
The sets are already compiled before they reach Aquasabi, so they can not be opened or altered.
