Black Venom Boulder Nano Stone
Black Venom Nano Boulder brings fluid contrast, organic flow, and visual drama to your scapes—naturally rounded igneous stones with a deep black glaze.
Black Venom Boulder Nano Stone is the smooth, water-shaped counterpart to WIO’s iconic Black Venom Stone. These igneous boulders have been softened over time, resulting in organic, rounded forms with a dark, glazed surface that enhances reflections and creates powerful contrast in both aquatic and terrestrial designs.
Their pitch-black coloration intensifies the greens of surrounding plants and mosses, allowing you to craft elegant compositions with striking simplicity. With sizes ranging from 3 to 10 cm, Black Venom Boulder Nano Stone are ideal for nano tanks under 40 L, where their balanced forms offer a sense of flow and calm among harder elements.
Each piece is hand-selected, pre-washed, and safe for livestock. While generally stable, these boulders may slightly raise pH and hardness-monitor water parameters in delicate setups. Whether used to soften hardscapes, anchor layouts, or create natural transitions, Black Venom Boulder Nano Stone offer elemental beauty in compact form.
