in my little tank I only have a printed background I made myself, it is taped to the outside of the tank and looks very nice.
The only thing that helps with reflection is making sure the light is brighter in the tank than it is outside in the room.
Also, when I put my background in when Guppy was in the tank he hated it, flared and complained for half hour before I gave up and removed it.
I later installed it on the tank when he was in a hospital tank, and he did not even notice when he was placed in the new tank.
This is printed on paper, laminated and stuck with tape to the outside of the tank, I think it looks pretty good. :)
