Spider Wood is very cool looking driftwood perfect for any aquarium. Each piece is unique and has web like branches with lots of character. Would be great as a focal point in a smaller tank or add a few for larger tanks. 

Spiderwood is a root from a water azalea. It is light weight and will need to be soaked for a couple of days in water to get it to sink. A nice benefit to spiderwood is that it doesn't leach as much tannins as other types of driftwood, so your tank water will stay clear.
