Technically, 99% of all frags in the trade still have to be considered wild. Much of what you find on frags in stores are just cut up colonies or frags from wild colonies.
There hasn't really been much actual successful coral breeding (=sexual reproduction).

Generally, I prefer to buy frags from "domesticated" (=well-acclimated) coral strains over frags from recently wild harvested colonies.
But I would also buy frags from recently wild harvested colonies if no domesticated alternative exists.
And in some special cases where frags just not do it, I would also buy wild colonies, like for example Porites with Christmas tree worms.
I would however never buy large wild harvested colonies of corals like Acropora and the like that can be easily grown from small frags.
