Volcanic rock formed when lava cools, Tropical Lava Rock is very porous, featuring lots of tiny holes throughout its structure. This makes it very light and also excellent for mosses to grow on and some plants to root into (they will need tying tot he rocks for some time before they attach by themselves). These stones are ideal for aquascaping.
