Ceramic Coral Frag Tiles are perfect for the propagation or fragging of hard and soft branching corals such as Acropora, Birdsnest, Montipora, Kenya Trees, Xenia, etc. Ceramic frag tiles are fired at nearly 2000 degrees in a high-temperature kiln making them 100% inert and safe. They never have to be cured and are shipped dry, and ready to use. They coralline up quickly and the post can be removed by many common fragging tools.
