Zooxanthellae are the organisms responsible for many of the colors we see in corals, I don't see why these organisms couldn't enter into a new coral, find a good environment, and sucessfully colonize the new coral... This is definitely something I'm going to start thinking about more carefully..... I have always wondered if name brand lineage starters had some kind of major hook-up with distributors where they got first dibs on EVERYTHING that came in, or if they somehow figured out a way to "add color" to "ugly" specimens.... I'm thinking about some of CB's lineages and maybe there is something to "in vivo" coral transfers...
