The first piece of driftwood I added is actually floating at the top. If you look at the top left, it stretches diagonally from the back left corner almost all the way across the tank. The piece itself is about 5ft long. The second piece is on the bottom left and it's about 3ft long. The pics are a bit dark so it's hard to make out everything, I'll try and get a couple more that are a bit brighter.
