Black Venom Stone from WIO is a striking rock that adds a touch of elegance to any aquascape or terrarium. These stones have a very dark colouring when wet and have a smooth surface that is not very jagged.

This igneous stone is ideal for creating an iwagumi layout or any other design that requires an impressive composition. The colour of the stone contrasts beautifully with the green of plants and moss, showing them off to their best advantage. Black Venom Stone can also be combined with other stones such as Silver Shadow Nano Rocks, Black Venom Nano Boulders and Heaven Sand. The combination of dark stone and light substrate creates strong contrasts in the aquarium and puts the focus on the hardscape compsium.

Black Venom Stone can slightly increase pH and hardness due to its alkaline nature.


  • Striking black colour with smooth surface
  • Creates excellent colour contrast
  • Emphasises the green of plants and moss
  • Ideal for iwagumi layouts
  • Can slightly increase the pH value and hardness


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.
