I read a article where they slice a zoa in half and spliced it with a different one and they mended together ..Has anyone ever done this or know of any more write ups on this?
There are cases I read, though I don't remember where, of stony corals falling and landing on others. When they came in contact, the dinoflagelates from one contaminated the other and infected it, causing a color change. I think it was in the Natural reef aquariums book, though I don't have a copy with me right now.
