Black Lava Rock with Hole
Black Lava Rock is created by the cooling of the volcanic magma and is an extremely porous stone commonly utilized by the aquascaping community. Black Lava Rock is dark black in color, lightweight, and has a very high surface area. The extra surface area will allow more space for beneficial bacteria to colonize, improving the overall health of the aquarium.
These pieces will have a pre-drilled hole, which provides the ideal environment for small cave-dwelling animals or shy by nature. Inside an aquarium, it will add lots of depth to your tank. You can attach regular black lava rocks to this rock to create more elaborate designs. You can find suitable glue here and regular lava rock pieces here.
