This listing includes 15-16LB per order. Black Lava Rock is a popular aquascaping stone that is commonly used in all types of freshwater aquarium setups. Loved for its porous texture, it’s arguably one of the best rocks to pair with epiphytic aquarium plants and mosses. You’ll often see easy aquatic plants like Anubias, Bucephalandra, moss, or ferns attached to this type of aquarium hardscape. Our favorites are Mini Pellia and Fissidens Fontanus!
Its lightweight density makes it easy to stack or balance when creating structured aquascape layouts. And because it’s relatively light, you’ll get more volume per pound compared to denser stones. It works wonderfully on its own or as a base foundation underneath your favorite aquarium wood. It is also very easy to break down if you need smaller pieces for layout accents or nano aquariums. Overall, Lava Rock is versatile and offers many benefits. Aside from its use as a hardscape layout material, it’s also great for cultivating a healthy colony of beneficial bacteria for better aquarium health and balance.

"The glass aqua team did a great job picking a variety of shapes and sizes. My order had a huge ranges of sizes from 1-2 inches to a large centerpiece rock around 9 inches long. This order was perfect for my aqua scaping needs for my 3-5 gallon tanks and I really couldn't be happier with the value for the price. I will definitely be ordering more when I get another tank."
