Right now I have frosted window cling film. Before that nothing but the wall and before that a cut open black garbage bag stretched tight to get rid of most of the wrinkles.
Don't put paint on until you have tried something temporary to see if that is the way to go! I was sticking all sorts of stuff in back of the tank to see what I liked best before I went out and paid the big bucks for the cling film.
