I maintain a 40 gal. tank with mostly members of the Doradidae Family. In my last house the tank was set up in such a way that the morning light came directly into the tank. Some of my fish had gotten to be about 6", and they were fighting over the darkest areas in the tank - which were under stacked rocks. They were capable of moving the rocks around, so I decided to get some backing to put on the tank that would block light. I went to my local pet store and the cost per foot of decorative tank backgrounds was expensive.
Instead of buying the backing from the pet store, I purchased a roll of window tint (for cars) and put it on the back and two sides of my tank. It cost me less than 1/3 the price and it has been working well for almost a year. I am in a new house where the sun does shine directly on the tank, but this background still keeps the tank dark, and prevents the fish from getting spooked every time someone walks by.
I hope this tip can be used by other PlanetCatfish members.
