Spider Wood XS # 9
Used by many Aquascapers around the world. Spiderwood can be made to look like roots of a tree, or flip it upside down to make a moss tree. The wood needs to absorb enough water before they will sink. Soak, boil or glue it to a rock and after one week, the wood will sink by itself.
