It involves designing and arranging the elements in a way that mimics natural landscapes, such as forests, mountains, or underwater ecosystems like coral reefs. Aquascaping is popular among aquarium enthusiasts and is often seen as a form of artistic expression within the hobby. It requires knowledge of aquatic plants, fishkeeping, horticulture, and design principles to create balanced and aesthetically pleasing underwater environments.
