This article wrote by Benjamin Law

Anyone who is interested in Nature Aquariums, you must see or have a stone formation layout style before. This is called Takashi Amano’s Iwagumi, developed by Takashi Amano san about 30 years ago. Takashi Amano, the founder of ADA came out the concept of Nature Aquarium, this was the revolution of aquarium world. He influenced the entire industry by using stone and wood to create layouts that simulation the wild nature.

Takashi Amano’s Iwagumi was an idea of using stone as the main aquascaping layout element. Amano defined that 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.

Check out the following video example of Iwagumi layout

Manten Stones are beautiful with the shape and line one the stone. It is one of my faveourite stone for aquascaping. But Manten Stonee’s price is rising so high now and it does not have new stock anymore.

Iwagumi Layout Beginning

So in start beginning in aquascape Iwagumi Layout, the first stone that place in the aquascaping layout would be the primary stone or the largest stone of the entire layout. This stone called Oyaishi in the layout. It would be placed off-center, and the stone tile direction of water-flow to give a natural feel. The second stone called Fukuishi, it would be placed opposite side of Oyaishi or other tilted direction of Oyaishi.

The third and other stones should be placed from large to small size, following the Oyaishi direction flow. We can pick 2 similar size stone for third stone child of First and Second stones, these stones called Soeishi. One can place follow by the Oyaishi direction, another should follow the Fukuishi to create a mountains feel-alike layout. As the other smaller stones, called Suteishi. Suteishi are going to be placed after Soeishi placed on the layout. We should follow the direction of the shape in order to make the aquascaping layout more natural.

Below is an example of how Iwagumi formation should be.

Basically, Iwagumi Aquscaping Layout is following the 3 rules in starting out the layout design.
Starting the layout by placed Oyaishi, Fukuishi, then Soeishi.
Again, there has no exact answer of putting stone left or right, back of the fish tank or front.
Aquascaping is all about creativity and inspiration. For example, you can place 2 Oyaishi if you have a large aquarium that creates left and right group of stone separately.
