Where to glue coral frag on porous, nonsmooth rock?

[danieljones8623]

I have had a couple coral frags in my tank for a bit. They seem pretty happy where they are, so I was thinking about gluing them to the rock. I’m just curious, do I need to be careful where I glue the corals, since my rock is real pitted and not smooth, or will the corals be fine with that?

I have always used the glue, epoxy, glue method, and it works when you don't have a flat surface.

Will the corals just grow over/into the holes in the rocks without issue most of the time?

Wondering this as well about the pits and crevices of my rock
