Mushroom corals are extremely hardy and easy to propagate. Even though they grow and reproduce rather rapidly in the home reef aquarium, some hobbyists actively frag them, cutting them into such tiny pieces that you might not expect them to survive the ordeal. After fragging, the priority is to get the corals attached to a substrate. To do this, simply place the fragmented pieces of coral onto a rock and secure them in place with the help of rubber bands. Others use mesh to hold the coral in place. Regardless of the method, super glue can’t be used, as the coral’s slime will prevent them from sticking to the glue.
