Well i started my research a bit later than I should have. I bought a 55gal tank alittle over a week ago(first FISH tank) brought it to the third floor apartment I live on and put my sand and water in it. Now that the water is clearing and I did lots of research on tanks I decided I want a black background on the tank. I saw that people have painted/spray painted ect... their tanks and I wanted to know if there is any other ways of making it black. I really don't want to have to empty it and move it back downstairs to paint it outside. I orginally thought that black trash bags cut and taped would work. But im not too sure that would work/look good ect... Anybody got any other ideas for me?
