The long variant of Seiryu Stone features an elongated, flatter profile that makes it ideal for building strong structure and directional flow in aquascapes. Its natural ridges and sharp edges help create height, depth, and dramatic lines, whether used as a main focal point or supporting stone. Perfect for Iwagumi-style or nature-style aquascapes that rely on clean composition and balance.

Compared to standard Seiryu, these aquarium hardscape pieces offer more reach and flexibility when forming ridgelines, cliffs, or layered terrain. The classic gray tones with white veining bring contrast and texture while keeping a cohesive, natural look. A great choice for aquascapers looking to create bold layouts with fewer rocks and more intentional placement.

Stones vary in shape, size, and density.

Notes:

• Seiryu may slightly raise pH and water hardness. Controsoil can help balance that out.
• We recommend rinsing stones thoroughly before use to remove any natural dust or sediment.
• Stone coloration darkens when wet.
