The rocks in your saltwater reef aquarium play two major roles, to host bacteria for biofiltration and to provide a safe habitat for your fish and other aquarium animals, including corals!  The habitat side of that equation is something many of us neglect or at least don't consider enough when building our own aquascapes.  

Ryan has built upon the popular NSA - Negative Space Aquascape and come up with a new approach that puts your fish first with a habitat-rich hardscape. Learn how to build your very own HNSA - Habitat Negative Space Aquascape!
