The substantial presence of Oyaishi

Hakkaiseki – a renowned viewing stone
A well-shaped Hakkaiseki has a commanding presence.

Creating a layout using locally produced rocks is another great way to enjoy an Iwagumi layout. The Hakkaiseki that are presented here are well-known viewing stones found at the foot of the Hakkai Mountains in Niigata. Those with the type of indentations called Mushikui arum below has one group of rocks. Using two grouping of rocks makes it easier in general to create a composition in a horizontally long aquarium. The planting of a single type of plant, such as Echinodorus tenellus, works well to accentuate highly prized. Such well-shaped Hakkaiseki have the stately and dignified presence of Oyaishi. These two Iwagumi layouts are the type of work that takes full advantage of the charm of Hakkaiseki. Both of the Iwagumi layouts were created using the same Oyaishi. The large panoramic aquarium above has two groups of rocks and the tall aquarie the presence of Hakkaiseki. The clean and simple composition of such a layout strongly brings out the spirituality of Iwagumi.

If the impression of Hakkaiseki as Oyaishi seems too strong, some plants, such as Eleocharis vivipara, should be planted in the background. Doing so can soften the impression of the rock.
