Nature Aquarium (Amano Style) Guide
The Nature Aquarium style, pioneered by Takashi Amano, recreates natural landscapes underwater using grouped plants, wood and stone with asymmetric, golden-ratio composition.
Overview
The Nature Aquarium style, also called the Amano or ADA style, is a planted-aquarium approach that recreates the mood of natural landscapes such as forests, hillsides and riverbanks. It uses an asymmetric arrangement of a relatively small number of plant species combined with carefully chosen wood and stone.
Origin and history
The style was introduced in the 1990s by the Japanese photographer Takashi Amano (1954-2015). Amano founded Aqua Design Amano (ADA) in 1982 and presented the Nature Aquarium concept through photo books, including works published in 1992 and 1994 and the Nature Aquarium World series. His background as a large-format landscape photographer who traveled through tropical rainforests informed the naturalistic look of the style.
Design philosophy
Amano's layouts incorporate Japanese gardening concepts, notably wabi-sabi, an aesthetic that values transience, imperfection and minimalism as sources of beauty. The composition usually centres on a single focal point positioned to reflect the golden ratio, with empty (negative) space left intentionally so the scene feels discovered rather than constructed. The arrangement is asymmetrical and uses masses of relatively few plant species rather than a large catalogue of types, which keeps the overall impression coherent and natural. Although the finished tank can look unplanned, achieving it requires considerable composition work.
Hardscape and layout
Stone and driftwood form the structural backbone of the scene, and the choice and placement of hardscape are decided before planting. The stone-only sub-form of the Nature Aquarium is the Iwagumi layout. Wood such as spider wood and redmoor is commonly used, often with mosses attached to soften the hardscape and suggest age and growth. Common layout shapes include concave, convex and triangular profiles that direct the eye toward the focal point and reinforce the sense of depth.
Plants and livestock
Planting tends to be dense but composed of comparatively few species arranged in masses. Carpets such as Hemianthus callitrichoides, stem plants like Rotala rotundifolia, and epiphytes including Anubias and Bucephalandra are typical, with mosses such as Vesicularia montagnei on wood. Schooling fish from genera such as Paracheirodon, Hyphessobrycon and Trigonostigma, together with shrimp like Caridina, are common choices.
Difficulty and maintenance
Dense growth under strong light usually requires CO2 injection, external filtration and regular fertilisation, making the Nature Aquarium a demanding, high-maintenance style. Frequent trimming is needed to preserve the intended proportions and keep the layout from becoming overgrown.
