Aquascape designs include a number of distinct styles, including the garden-like Dutch style and the Japanese-inspired nature style. Typically, an aquascape houses fish as well as plants, although it is possible to create an aquascape with plants only, or with rockwork or other hardscape and no plants.Although the primary aim of aquascaping is to create an artful underwater landscape, the technical aspects of aquatic plant maintenance must also be taken into consideration. Many factors must be balanced in the closed system of an aquarium tank to ensure the success of an aquascape. These factors include filtration, maintaining carbon dioxide at levels sufficient to support photosynthesis underwater, substrate and fertilization, lighting, and algae control.Aquascape hobbyists trade plants, conduct contests, and share photographs and information via the Internet. The United States-based Aquatic Gardeners Association has about 1,200 members. contrasting approach is the "nature aquarium" or Japanese style, introduced in the 1990s by Takashi Amano. Amano's three-volume series, Nature Aquarium World, sparked a wave of interest in aquarium gardening, and he has been cited as having "set a new standard in aquarium management". Amano's compositions draw on Japanese gardening techniques that attempt to mimic natural landscapes by the asymmetrical arrangement of masses of relatively few species of plants, and carefully selected stones or driftwood. The objective is to evoke a landscape in miniature, rather than a colorful garden. This style draws particularly from the Japanese aesthetic concepts of Wabi-sabi, which focuses on transience and minimalism as sources of beauty, and Iwagumi which sets rules governing rock placement. In the Iwagumi system, the Oyaishi, or main stone, is placed slightly off-center in the tank, and Soeishi, or accompanying stones, are grouped near it, while Fukuseki, or secondary stones, are arranged in subordinate positions. The location of the focal point of the display, determined largely by the asymmetric placement of the Oyaishi, is considered important, and follows ratios that reflect Pythagorean tuning. Plants with small leaves, such as Eleocharis acicularis, Glossostigma elatinoides, Hemianthus callitrichoides, Riccia fluitans, small aquatic ferns, and Java moss (Versicularia dubyana or Taxiphyllum barbieri) are usually emphasized, with more limited colors than in the Dutch style, and the hardscape is not completely covered. Fish, or freshwater shrimp such as Caridina multidentata and Neocaridina heteropoda, are usually selected to complement the plants and control algae, but for reasons of minimalism the number of species are often limited.
