I purchased a decent amount of driftwood from Tom Barr and have one piece that was just too much for my current tank. The green that you are seeing on the wood is just dried up Salvinia that was stuck to the wood when I took it out of the tank. It must have been in my tank for about a month so I would guess that a good amount of tannins are now gone. There are small what appear to be worm holes which would be perfect for shrimp. The piece is about 21 inches tall...my shoe size is 9 so I threw it in for reference. I live walking distance from the MetroNorth in Greenwich CT. It's 42 minutes on the train from Grand Central.
