There are some other advantages:

• Acidifying effect: wood lowers the pH of your aquarium
• It is healthy for fish with a “cellulose requirement”
• It is a handy outlet for fish eggs
• It offers many shelter options for fish (and shrimp)
• It is a good bonding base for Epiphytes such as Java fern or moss

That why you need wood in your freshwater aquarium.

Aquascaping may be a form of art in which imagination and creativity play an essential role, but mastering the backbone of this process is elementary if you want to be successful. Measure is very important in nature, and aquascaping makes no exception.
