Tidepool Tim says, "Cobbly seabed substrate is perfect for aquariums and touch tanks housing marine invertebrates in particular. Rocks are preferred anchors for many species living in intertidal zones, often serving as seaweed holdfasts. Snails and mussels also attach themselves to rocks. The stones are granite, slate, limestone, quartz and more."
