I, personally (( and this is just my opinion )), don't believe that -- they (( the angels )) have been nipping at corals for thousands of years, just being tank raised/breed for one generation is going to stop that.
It is similar to tank breed/raised clowns -- they are still hosted by anemones, even if they never saw one until released into our tanks. Instinct is a very very powerful thing, my tank breed A. polymnus were hosted by an S. haddoni (( natural host )) within minutes of being released.
