WIO Bumblebee Boulder Nano Stone brings warmth, harmony, and a rich natural palette to your scape — smooth sedimentary boulders in natural yellow ochre tones, perfectly scaled for nano compositions that evoke sun-drenched riverbeds and warm, inviting landscapes.

Bumblebee Boulder Nano Stone carries the same characteristic warm yellow ochre tones as the full-size Bumblebee Boulder — a smooth, slightly textured sedimentary stone that creates a beautifully harmonious scape. Its warm palette creates high visual impact due to its richness in shapes and colors, and pairs effortlessly with matching gravels and warm sands.

Sized between 3 and 10 cm, Bumblebee Nano Boulders are ideal for nano tanks under 40L. They may raise pH and hardness slightly; regular water changes are enough to keep hardness under control. Pre-washed and ready to use.
