Is it really cloning though?
What kind of corals are we talking about?
In my experience, with sps anyways, the longer they have been in captivity, the better they have done in my tank. Some of the frags I have got from a member here who has had some of the colonies for 10+ years, are pretty much bullet proof.
But I don't really think its cloning, with sps anyways, because the new frags are just clipped from the tips of the original colonies and then attached to a plug (whether its a frag from another reefer or a frag taken from the ocean recently). So the "new" coral has not been "man made" or genetically made. That's just my logic but maybe I am missing something?
