I didn't have any more issues with the clowns toppling the corals.
All seems right in the world of my aquarium since moving the sand into the clownfish area of the tank. The clowns are back to bickering with themselves and leaving the other fish and corals alone.
Yes, Growing on the back wall of my tank there is an orange monti digitata (upper wall) and a monti cap (lower wall). Both are growing flat and spreading across the wall versus growing horizontal out into the water. Very strange, particularly from the orange monti digitata, but that is what they are doing.
There is also a Cyphastrea growing right in front of them.
