Venom Boulder Nano Stone
WIO Venom Boulder Nano Stone, brings fluid contrast, organic flow, and visual drama to your scapes—naturally rounded igneous stones with a deep black glaze.
WIO Venom Boulder Nano Stone, is the smooth, water-shaped counterpart to WIO’s iconicVenom 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, 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, Venom Boulder Nano Stone offer elemental beauty in compact form.

- Rounded Texture: Naturally smoothed for organic compositions.
- Contrast Element: Amplifies the visual intensity of plants and moss.
- Pre-Washed: Clean and ready to use, no soaking required.
- Safe: Inert for most aquatic animals, including shrimp.
- Water Chemistry: Calcareous-may raise pH and hardness slightly.
- Versatile Use: Aquariums, terrariums, paludariums, bowls.
- Packaging: 2 kg bag with assorted boulders.
- Pairing Tip: Combine with Black Venom Nano Stone and gravel for cohesive layouts. For refined details and contrast transitions, add WIO Accents Black Chips.
- Preparation
– Rinse briefly to remove any transport dust.
– Pre-washed, no soaking required.
- Placement Tips
– Use larger boulders as anchors or soft focal points.
– Cluster smaller ones near roots, moss, or contrasting stones.
– Avoid direct contact with glass-place over substrate or WIO LandForms.
– Secure with WIO ScapeGlue with FuseColor for stable layouts.
- Layout Ideas
– Ideal for Zen-inspired or riverbed compositions.
– Create soft contrasts in otherwise angular hardscapes.
– Use as centerpieces in minimalist terrarium or paludarium settings.
- Maintenance Ideas
– During cleaning, gently use WIO cleaning tools to lift any debris from stone surfaces.
– Control any alterations in pH and kH by regular water changes with osmotic or soft water, or by using WIO water treatments.
Notes
– Each bag contains a unique mix-expect natural variation in shape, gloss, and texture.
– May increase water hardness over time in soft water systems-monitor accordingly.- Preparation
