maybe a dumb question because I see it in other people's pics but just to clarify. When things are aggressive, "sting" or are capable of harming other corals, the same species can touch correct? For instance I have a few different acans and would like to group them together where they will most likely touch one another. That's ok right? I know zoas can. I've seen it with frogspawns and a few others. Curious about the acans
