Red Lava Rocks for Aquascapes and tank decor. Each piece will be 3-8 inches in size. Create amazing looking mountains, or even cover them with moss and plants for added POP to your tank design. Lava rock is porous and creates a brilliant habitat for beneficial bacteria to live and thrive in. As well as pockets for micro-organism growth allowing grazers such as shrimp / algae eating fish to feast upon. 

All Rock ship Priority USPS for fast arrival to meet your project needs.
