Seascape two months ago was talking about fragging yuma rics. Said it was harder than normal shrooms. But that it did work. Cut and let heal is the gist I got from the article. It said that the tissue was alot harder to make a clean cut thru and recomended a very sharp blade and firm pressure to make a clean cut. Beyond that it seemed to be same as always. Stable clean water, good light, and coral that has been doing well in your system for a good amount of time. HTH Steve
