So I wanted to get some of yall's opinions on coral placement. First let me start by saying I know that some corals sting and should be kept away from surrounding corals and that some corals need certain amount of light. This question is for those corals that don’t sting and that can do well almost anywhere in the tank. How do yall go about placing them in yalls tanks? Do you worry about how big they are going to grow and if they are going to grow into another coral? I have seen a lot of tanks that seem to have a lot of random corals growing all over the place. I can imagine that it would be hard to separate a coral once it has encrusted on a rock. The reason I’m asking is because I currently have several SPS frags encrusted on a piece of rock along with an encrusting rainbow montipora. I also have a lot of soft corals on rocks that have a lot of space left over that I could add zoas to or SPS to. I just don’t want to cause any problems once they start touching.

On another note, do you guys worry about zoas growing in random places in the tank? I know some try to isolate them but I have been thinking about placing my zoa frags throughout the whole tank to fill in empty spots. I just want things to grow and fill out and will frag as needed.
