Lava Rock Pebbles / Boulders - 5kg

Shape your aquascape with natural lava rock

Give your aquarium a striking, grounded look with sculpted lava rock. Years of water movement have softened the boulders’ contours, while their porous-looking texture creates a mature, natural feel alongside lush green plants.

Choose Pebbles or Boulders

Select the Pebbles or Boulders option to suit your layout. Each piece is natural stone, so shapes, sizes and colours vary. Pebbles approx range is 4cm-15cm, and Boulders are approximately 15–25 cm; we’ll pick a varied range where our available stock allows.

This listing is for 5 kg.
