I just picked up a biig piece the other day and put it in my Sa/Ca tank, the tank is 130gallon,26"wide. I had a bunch of other small pieces but i think this looks wasy better, lots of branches on it and little holes.
when you use the flash on the tank make sure you shoot at an angle then the photo should come out better. I can't really see the wood. I think it looks big could look really neat turned the long way so the branches stick out the top.
