We spied this new frag piece at the Midwest Frag fest in Rockford, Illinois. The piece which is actually two pieces is a clever way to entice encrusting corals to well do their thing, which is to crust up substrates. You mount the coral in the center plug, wait for the coral to grow over the plug and can either take the plug out by means of picking around the edges and giving it to your friends with a frag disk so they can enjoy the encrusting coral or you can just leave it be. Two of these reef disks come to a box and a box will run you a low $9 atMidwest Saltwater.
