if you have ricordia floridas, feed well and the mushroom will develop multiple mouths. cut between the mouths and place a slim piece of plastic in between so the mushroom will not fuse back together. once all the pieces have healed and shaped itself into an individual mushrooom, cut the mushrooms from its base leaving the bottom of its foot attached to the rock. place the removed mushrooms into you
refugium/sump in a cup with coarse gravel. once the mushroom has attached to the coarse gravel, glue the attached mushroom onto a piece of rock. allow some time and the mushroom can be returned to the main display or glued to a larger piece of rock along with other mushrooms. in the meantime, the bottom of the feet of the mushrooms you sliced of at the base will have begun to grow a new head.
