@kingranch2003 the corals will take care of it for you. You just need to mount them to the rock in an appropriate place. It's best to either do it right away or wait until you see the base starting to encrust out on the plug. The advantage to right away is that it is easier to mount them before they start to spread, the downside is that they may be harder to acclimate if you don't have experience with that type of coral (getting it in a spot it likes).
Once they start to encrust their plug they are actively attaching themselves to the surface. How that happens depends a lot on the type of coral. For instance a birdnest will typically start some downward branches that eventually fuse to the rock while a digitata will typically just get wider and wider at the base encrusting the rock. I let my Bubblegum digi go a bit too long on its plug so I'm just going to cut the post off of the plug and mount it to a rock. I prefer to remove the plugs or remount them to a larger plug/tile early on but I've been negligent lately.
Here is a shot of the Bubblegum right after I moved it back to the DT from the hospital tank on Dec 30th 2024, notice that while it is firmly mounted it hasn't really started to encrust the plug very much. This would have been the ideal time to mount it but the DT wasn't really in good condition.
Here is the same coral a day or two ago. Breaking it off of the plug now is possible but I don't want to stunt its encrusting so I will instead cut the post off and mount the digi and the plug base onto a rock.
Hope this helps.
