I have an iwagumi setup in my 40 gallon.
Read up about Iwagumi here on planted tank.net
You want to use rocks in the numbers of 3,
5, 7, or 9, not even numbers. In Iwagumi
there's the rule of thirds, that plays an
integral part of the composition. It's all
about composition and type of ground
cover you use.
