Please describe what ever logic there is for driftwood location and placement. I have 3 pieces I am getting reading to put in a new 55 planted tank. One large triangle shaped that I am thinking maybe a center piece and the other two are more like limbs. They are Malaysian wood pieces. No doubt the location I pick will be wrong so I seek the wisdom of the group. The limb pieces do not have any slate to hold them in an upright position. I have plenty of sheet plastic at my disposal so I may position them as coming out of the substrate.
