Tiger wood is another great type of wood to use for aquascapes in freshwater aquariums. It is very branchy and voluminous. It is typically heavy enough to sink on its own. It will not discolor your tank either. The size and shape vary piece by piece.
Small (8"-12")
Medium (12"-18")
Large (18"-24")
Extra Large (24"-36")
Premium pieces are especially attractive specimens with unique qualities often sought after by aquascapers.
