Colored backgrounds for tanks???

Most all my tanks have dark backgroung. Some are tinted glass or acryllic, the tank back panel itself. Others are pinted on by me or roll style.

Some have sheets of tinted plexiglass positioned behind them that can be chamnged out.
 
I guess I'm super-cheap.... I have a cut open brown paper grocery bag behind my tank! I like the nice neutral brown, and it's matte so it doesn't reflect light. :cool2:
