Ryuoh stones have a variety of appearance due to the white line and wrinkles. Their forms are suitable for an iwagumi layout which evokes a reef. For making such layout, an important point is to pay attention to the ridge line and the continuity of stones.
We recommend 2 pounds of stone for every gallon of water your tank holds. A 5 gallon tank would need 10 pounds, 10 gallon requires 20 pounds etc. Of course this is just a recommendation, the amount of stone needed will depend on your plans. Its always nice to have options too!
How we choose stone
Most stones range from 6 cm - 25cm and are chosen randomly for what we think will work well together. But if you would like smaller, bigger, rounder, sharper or different colours, just request when you check out. We'll do our best.
