Any aquascaper who is a fan of Nature Aquariums must have come across Takashi Amano’s Iwagumi, or ‘stone formation’ style. He developed it about 30 years ago.

When Takashi Amano was in his early 20s, he became interested in creating an aquatic layout using rocks. So he studied Suiseki, the Japanese art of stone appreciation and Bonseki, the art of creating miniature landscapes on a black lacquer tray — art-forms passed forward through an entire millenium. Neither could Amano escape the influence of the quintessential Japanese garden, in which rocks are the “bones” of the entire layout, and of which it is said that once the rock formation is placed properly, the rest of the layout will simply fall into place. These studies and his own experiments aided him in establishing the Iwagumi style.

The first rock to be placed in an Iwagumi aquascape is the primary rock or largest rock, the Oyaishi, and it is always placed off-centre, in accordance with the rule of thirds. It is also often slightly tilted in the direction of the water flow, to give it more of a natural feel, as any tall flora will also move in the same direction. After the Oyaishi, the second largest rock is placed, the Fukuishi. The Fukuishi is placed on either the left, or right side of the Oyaishi, and its role is to balance out the Oyaishi and to create tension — a characteristic seen in all Iwagumi aquascapes. The third largest rock follows the Fukuishi, the Soeishi. Again loosely following the rule of thirds, it is placed in a position that accentuates the strength of the Oyaishi. The fourth largest rock is the Suteishi, and it is placed in an area that compliments the entire rock formation, because its function is to assist in bringing all the different rocks ‘together’, to form a whole. Despite its function, the Suteishi is not meant to stand out from the rock formation as a whole. In fact, it is frequently hidden by flora, which is why it is also known as the ‘sacrificial stone’.
