Dragon Stones

Intricate, Lightweight Beauty for Stunning Aquascapes!

Dragon Stones, also known as Ohko stones, are lightweight, clay-based rocks with a rugged, scale-like texture, perfect for creating lush, root-style planted layouts. Their porous, crevice-rich surface and neutral chemistry make them a favorite for Iwagumi and nature-style aquascapes in freshwater tanks, terrariums, and paludariums.

Key Features:

• Natural Ohko Dragon Stone: Hardened clay (mudstone) with intricate, scale-like texture for a dramatic, natural look.

• Lightweight & Porous: Low density (~1.6 g/cm³) allows easy stacking into tall cliffs or overhangs without stressing glass tanks.

• Inert & Aquarium-Safe: Negligible impact on pH or hardness, ideal for shrimp, sensitive fish, and planted setups.

• Green-Brown Hues: Earthy tones with tan highlights blend seamlessly with plants and driftwood.

• Deep Pockets & Ridges: Perfect anchor points for mosses, ferns, and Bucephalandra, enhancing lush growth.

• Unique Shapes: Irregular 5–20 cm pieces (0.2–1 kg) add instant depth and visual interest.

Why Choose Dragon Stones?

Dragon Stones offer an iconic crevice texture for creating natural caves, overhangs, and cliffs, ideal for Iwagumi and nature-style layouts. Their lightweight nature ensures safe, large-scale structures, while neutral chemistry keeps water parameters stable for delicate livestock, making them a top choice for planted aquariums.

Usage Tip:

Use small Dragon Stone chips to fill gaps between larger pieces, locking formations and providing extra surface for moss to grip, creating a cohesive, natural aquascape.
