Hmmm. This is good to know. Rics should be placed away from corals that might fall into them. What about shrooms of different varieties grouped together? For instance I’m slowly building a Ric Rock. So far I’ve attached several different kinds of shrooms together on one small rock; one green Ric, a purple, a green and a watermelon all close together. As of now the green Ric has begat one youngster and it is touching or coming up underneath a watermelon shroom. Will this eventually be a problem? If so how do guys like the one selling his “Rare” collection on ebay group these colonies together?
