I have a really big rock that is about 50% covered with sunset montipora, and on the other side some zoo's have resurfaced that I killed to put the monti on it. This has stopped the growth of the monti for now, and has given me some ideas. I'm curious if anyone has one rock with multiple monti's on it? What happens when they touch? Will one take over the other? Just curious. I may leave zoo's in the middle to separate two different monti's or just kill the zoo's and the let the sunset take over the whole rock as I intended. Let me know your experiences.
