Medium Size: Approximately 700g / 16cm x 12cm per piece.
Tropical Lava Rock is a light weight igneous rock formed by the solidification of magma.
Each piece is individual and would look lovely when used as part of an aquascape.
Because of its rough texture this rock is ideal for mosses to grow on.
Please Note: We fit as many of this size into your order and then make up the remaining weight with smaller pieces.
