The Black Venom Nano Rocks from the WIOdecor Nano Rocks series by the manufacturer WIO are pitch-black, rounded stones. They fascinate with its smooth, black surface and are suitable for effective design variations in the aquascape. Together with green plants, especially those with soft shapes such as needle cress, these stones bring a particularly contrasting look to the aquarium.


  • Rounded stone in pitch black
  • Interestingly textured surface
  • Idealer Stein für Iwagumi Layouts
  • This rock can slightly increase the pH value and the water hardness
  • Available in 2 kg packages


These stone sets are untreated natural products. It is recommended to clean and rinse the stone 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.
