WIO Black Venom Stone Kit is a striking igneous stone with a jagged surface that creates excellent color contrast in any aquarium or terrarium. Its vibrant pitch-black color and smooth black-glazed surface make it stand out from other stones, while the maze-like texture creates an intriguing element that adds depth and complexity to any layout.

Black Venom is perfect for creating an Iwagumi layout or any design that requires a high-impact composition. The stone's color contrasts beautifully with the green of plants and moss, making them stand out even more. Mix and match with Shadow Nano Stone, Venom Nano Boulders, and Heaven sand to create a stunning and unique design.

Black Venom Stone is available in dark grey in dry form and transitions to vibrant pitch-black underwater, creating a beautiful and natural aquatic environment. The stone may raise pH and hardness slightly due to its alkaline nature.
