I'm setting up a cube aquarium in a corner, looking for a really clean look, rimless, hanging pendant etc. the stand is white, I'm hoping to get a white fixture, but the wall behind the tank is gray. I've painted past aquariums with flat black krylon fusion and was very happy with the result, but I'm not sure black will be good in this situation. Would white be ok? Or should I just leave it clear? Any examples of tanks with a white painted background? Thanks!
