Caribsea Liferock Fraggerz 10Pk

These fist sized pieces of LifeRock each contain a single through hole perfectly sized for receiving frag plugs. Fraggerz are the easy way to isolate individual corals and prevent unwanted spreading from rock to rock. These beautiful rocks make corals not only easy to place by holding frags securely (hides ugly plugs too), but allow easy re-location around the aquarium as corals grow. Fraggerz can also be easily placed on exiting rock structures, or left free standing in substrate.
