The Tunze Magnetic Coral Frag Rock is the best way to show off your frags in a display tank setting. Grow your coral frags, or to add to your aquascape anywhere on the glass in your aquarium. The highly porous ceramic rock has a very powerful magnet that is carefully embedded into the back side of the rock. Holes are then strategically made allowing your coral's frag plug to securely be placed in the rock. The holes in the rock will fit the most common types of frag plugs, and other mounts.

The Tunze Magnetic Coral Rocks are hand made, and will be slightly different in appearance, and overall size from rock to rock. They are made with a super porous ceramic material that does not require curing and will grow natural coralline algae and other life just like live rock.
