My tank has more or less finished cycling. So I want to make sure the rocks are in the best place before I add fish. I currently have the rock in this set up, it’s all dry rock. Someone advised to have one piece of rock slightly separate for when I get corals.
I was thinking of placing the middle piece on tops of the pieces either side to form an arch. But I’d need to secure them properly if anyone has any better suggestions?
