Plate Coral location

[reef_junkies]

My plate coral seem to be doing better, their color is good, otherwise look healthy, they have good extension during the day, my only concern is a little selfish, I had them on a live rock shelf mid way in my tank and decided to move them to a different live rock at about the same height, the only difference is they are on a 45 degree angle so I could see them better. Will they survive being positioned up like this? or are they best left flat? Can't seem to find any info on location and just wondering if this is ok? Any imput would be appreciated.
