they are most likely bleached. The zoas probably bleached due to the tranfer and change of water conditions.I had this happen to my own when expanding my tanks and the water was really cold.Just be aware. I could have easly sold them as blizzards..but really they where AOG's that bleached. If you notice in LFS's ..they always seem to have some kind of coral that has some different colors than normal. Just today,i notice this happening here at a LFS near me....a bad condition coral that was loosing its color due to the lights. Just a FYI....Good Luck
