In the primitive age, human beings were part of Nature, and Nature was nothing special for human beings. However, as civilization develops, people are distance from nature and sometimes came into conflict with it. In the working of nature, trees wither, and decay, and only pulp remains. Remains of the trees are drifted by water, and becomes part of the natural landscape. Such a simple landscape moves our mind, because our memory of primitive age might be recalled.
Driftwood is the layout material most often used after stone in Natura Aquarium. Basically a few pieces of driftwood is combined and used as a backbone of the layout. Sometimes only one piece of driftwood is used in a tank, but even if it looks like a single piece of driftwood is used, there are many cases several pieces of driftwood are combined in reality. It is normal there is good part and not so nice part in a single piece of driftwood. By combining some pieces of driftwood, it can cover weak points of the driftwood. The most important point for combing driftwood is to choose same color and feeling of driftwood. It makes uncomfortable feeling if it is used different color and feeling of driftwood, even driftwood is collected from same area or same sort of driftwood is used. Keep in mind above point when selecting the driftwood.
