Dragon Rock - 1 KG

Dragon Rock, also known as Ohko Stone, is one of the most loved hardscape materials for freshwater aquariums and planted tank aquascapes. Its signature weathered surface, full of grooves, holes, and layered texture, creates a rugged mountain-style look that works beautifully in nature layouts, Iwagumi-inspired designs, shrimp tanks, and terrariums. Sold here as a 1 kg quantity, it is a practical option for hobbyists who want to add detail to an existing setup or build a custom rockscape piece by piece.

This stone is especially popular because it gives an aged, natural appearance without looking artificial or overly polished. The irregular shape helps create depth, shadow, and visual contrast in aquascapes, while the many crevices can be used to anchor moss, accent epiphyte plants, or form hiding spaces for shrimp and small fish. As each piece is naturally formed, no two rocks are exactly the same, which makes every layout more unique.

Key Features

• Material: Natural Dragon Rock / Ohko Stone with a clay-based, heavily textured surface.
• Size / Shape Notes: Supplied by weight as 1 kg; individual pieces may vary in shape, thickness, and contour because this is a natural hardscape material.
• Hardness: Firm decorative stone suitable for aquascaping structures, accent work, and layout building.
• Safe For: Suitable for freshwater aquariums, planted tanks, shrimp setups, paludariums, and terrariums when cleaned before use.
• Visual Style: Earthy brown to tan rock with dramatic holes, ridges, and dragon-scale-like texture that gives a wild natural look.
• Aquascaping Use: Great for mountain layouts, cliff effects, cave formation, focal points, and combining with carpeting plants or driftwood.

How To Use

• Preparation / Curing: Rinse thoroughly before adding to the aquarium to remove loose dust, clay residue, and transport debris. A soft brush can help clean deeper grooves.
• Placement: Position larger base pieces securely on the tank bottom or on an egg-crate/support layer before adding substrate, especially in heavy rock layouts.
• Water Effects: Dragon Rock is generally chosen for planted freshwater tanks because it is often considered more aquascape-friendly than many decorative stones, but natural materials can vary, so monitor water parameters in sensitive setups.
• Planting Tips: Use the natural holes and cracks to tuck in moss, Bucephalandra, Anubias, or small epiphytes for a mature aquascape look.
• Maintenance: During rescapes or deep cleaning, gently rinse the rock in old tank water or clean water to remove trapped detritus without using soap or chemical cleaners.
• Layout Planning: Mix multiple weights and shapes to create better scale, stronger perspective, and a more natural composition instead of using similarly sized stones only.

Because Dragon Rock is a natural product, colour tone, texture, and exact form will vary from piece to piece. This variation is part of its appeal and helps create a more realistic aquascape. For best visual results, combine several pieces of different sizes and test your arrangement outside the tank before final placement.
