So is the tissue of the coral coming off? if so is that starting from the top or bottom? Is the coral turning white but not loosing its tissue? Is their white spots forming on the corals tissue but the tissue is still in place??

sumtimes that happens when the bottom part can not get any light now if these are frags are they real close to each other because they will fight or maybe aneomes hitting them just a couple of ideas

Then it is most likely as chris says. as the coral grows some branches shade other branches also some of the bottoms of the lower branches dont see the light anymore. This causes the zoox and pigments to migrate to other areas on the coral that is still recieving light.
