In recent times, one of the most striking questions I found myself making is related to the actual differences between Nature Aquarium and Diorama Aquarium. Yes, I am doing explicitly this splitting between the two because they differ in the very roots of aquascaping, which are utterly ignored when considering both types of works. You may ask many hobbyists around, even professionals, and you will find rarely a coherent or clear answer about what separates both branches.
The reason why this happens is because, historically speaking, the Diorama Aquarium has emerged as a splint of Nature Aquarium, which has grown up to overpass in popularity to his former discipline. This splint has evolved so much in the basics of the Nature Aquarium that they are no longer connected.
