I never took pics of the setup. It was simply sand colored floor tile (10" x 10") that I drilled oddly-spaced holes with spacing between the holes of 3.5" - 4.5". After the epoxy-cured 1" - 2" diameter x 22" - 24" tall bamboo poles cured, they were screwed to the tile using SS screws. A few had to be epoxy sealed to the tile because they didn't have enough wood for the screw to bite in. The tiles were then placed in the tank with a blind divider of either rock or plants to reduce the view of one dat "station" to another.
I've seen similar setups where instead of bamboo, the setup had mangrove root or driftwood.
My dats seemed to enjoy "dancing" and weaving through the bamboo. It most likely gave them the same sense of security they had in the wild weaving among estuarian roots and log-falls.
