Jordan,
Do you have a picture of your current setup?
Corals don't really like running into each other. You wind up either with chemical warfare (coral WMD's, if you will) or physical warfare (stinging sweeper tentacles).
They get large with feeding, light, and age (depending on the coral). Then, they run into each other
I really don't like rearranging LR unless absolutely necessary. The basic rule of thumbs for arranging LR is more a 'negative' rule than a 'positive' one. The 'negative' being "don't stack your LR like a brick wall, and don't heap it together like a big pile." Stacking the rock so pointy edges dig into crevices, forming an airy, open structure with caves, crevices, nooks, crannies, canyons, etc. is considered good. But this requires reasonably irregularly shaped rocks. Another 'negative' rule is "don't stack the rock with small rock underneath and big rock on top unless you want the whole pile to collapse unceremoniously"
Stacking like Stonehenge is probably good. If you have glass tanks, I like taking a large slab-like piece, and lean it against the back wall, to create a natural hiding place for my fish. I like creating large piles in the middle so that the fish can swim around the piles (like a Fig. 8...). I think if you click on my profile, you can find my web site, and I think I posted there an old picture of my tank.
Regards,
Hy
