red montipora placement on a stand

So yesterday i came home and red montipora came off its stand and was laying on sand " idk how to explain it but like face first or the red front was toward the sand". i kinda figured on of the fish bump it but i fliped it over and the red was starting to turn white so i don't know if it ok or not. but i was gonna re glue it to a new rock but idk if theirs a special angle it need to be at? before it fell off it was at about a 25-30 Degree angle is that ok? or does it need to be more flat? i have it toward the middle of the tank and ive had montipora for about 2 1/2 months

 

Angeled or perpendicular to the rock is fine. Placement perpendicular allows greater lighting to the surface area of the coral.

 

Great thank you
