So I have a 9x3x2 tank that I want to put a couple rays/catsharks in but I also want to have a good amount of mixed reef going on. Anyone got any ideas on how to keep as much of the sandbed open as I can while maximizing coral space and still being structurally sound? Thinking some trees and arches or overhangs but if anybody has some good pictures of a similar scape it would be so helpful!
