just wanted to know how do you get your backgrounds to stick properly to the back of your tanks and what have you used so far? i've used a piece of construction paper from the dollar store but when I cleaned the tank, some water would spill and stuff, resulting in the paper to get stained and warp because of the water.
So I went to a backdrop that they sell at the pet shop, which are nice, but I can't get it to stick properly with just tape. Wherever there's space between mytank and the sheet, it looks different than if the background is right up against the glass. Is there some technique that i'm just too dumb to figure out?
