Imported Japanese driftwood As Branch wood has many small branches, it looks nice just by placing it in a layout. But it is cut artificially at the end of branches and roots to avoid any injury to fast moving fish, so you can keep the natural impression by attaching Willow moss to cover the unnatural sections. *A stone or something to hold the Branch wood will be needed for initial stage as it may float due to buoyancy.*Saprolegnia may appear during the initial stage. If it occurs, suction them out with a small tube frequently.
