The Tunze Magnetic Coral Frag Rock is the best way to show off your frags in a display tank setting. Letting you place the rock anywhere on your glass in the tank, and easily remove, add, and transfer frag plugs in and out of 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 just like live rock.
