Lava rocks are just as beneficial for your aquarium as they are fun! They help with tank filtration, as their porous texture makes for great landing spots for beneficial bacteria to latch onto and form colonies. Lava rocks are a light-weight rock that can also be used to attach Anubias, Java Ferns, and Bucephalandra to.

These small Lava Rocks have pre-drilled holes that are perfect for embedding plants. 

• Approximate lava rock size: 1"x1.5" - 1.5" x 2"
