"Live rock" is rock from the ocean that has been introduced into a saltwater aquarium, which gives the closed marine system multiple benefits desired by the salt water aquarium hobbyist. The name sometimes leads to confusion, as "live rock" itself is not actually alive, but is made simply from the calcium carbonate skeletons of long dead corals, or other calcareous organisms, which in the ocean form the majority of coral reefs. When taken from the ocean it is usually encrusted with Coralline algae and inhabited by a multitude of marine organisms. The many forms of micro and macroscopic marine life that live on and inside of the rock, which acts as an ideal habitat, give it the name "live rock." Check out our selection of live rock.
