4–8 Inches Natural Black Lava Rocks, 4 PCS Medium Aquarium Stones for Aquascaping, Fish Tank Hardscape, Planted Tanks, Terrariums & Reptile Decor (Medium 4–8 in)
MEDIUM ROCKS FOR BALANCED LAYOUTS: This 4-piece medium lava rock set includes natural black volcanic stones measuring about 4–8 inches. The size is ideal for creating main accents, midground structures, raised slopes, and balanced aquascape compositions.
BOLD BLACK COLOR & RUGGED SHAPE: The deep black tone and irregular volcanic texture create a natural, dramatic look in planted aquariums. These stones pair well with sand, gravel, driftwood, aquatic plants, and smaller decorative rocks.
POROUS SURFACE FOR PLANTED SETUPS: The porous texture offers surface area for beneficial biological activity and helps provide attachment points for mosses, ferns, anubias, and other aquarium plants.
VERSATILE FOR AQUARIUMS & HABITATS: Suitable for freshwater aquariums, planted tanks, shrimp tanks, terrariums, paludariums, and reptile enclosures. Use them as centerpiece stones, support rocks, edge stones, or structural pieces.
APPROXIMATE WEIGHT & NATURAL VARIATION: The set weighs about 3.4 kg / 7.5 lb excluding packaging. Since these are natural stones, each piece varies in size, shape, surface holes, and texture, giving every aquarium layout a unique appearance.
