In a planted aquarium, hardscape materials can substantially change the look of the overall aquascape. Black River Rock from Caribsea allows you to create a spectacular backdrop for your plants and fish and the dark color helps bring out the best coloration.
Available in 12 and 25 lb sizes, you can expect to receive approximately 7-9 and 19-22 rocks, respectively. Rocks are usually between 3-5" in size. Because these rocks are all-natural, the exact shape and size may vary slightly.
