Black Venom Boulder mesmerizes with its stunningly vibrant pitch-black color and smooth black-glazed surface.

It adds depth to your aquarium or terrarium and provides a stunning contrast that magnifies the green of your plants and mosses.

To achieve a high-impact composition, mix and match Black Venom Nano Boulders and gravels with Heaven sand.
