Poll - Reef Background Color

[tt101]

this poll couldn't have come at a better time. im trying to see what color to paint the back or if im going to use a vinyl background. both colors have their merits. like i think black helps make fish pop but blue really brightens up a tank and gives it a more serene feeling. you could paint the back light-ish blue and the sides a darker blue to give the effect of a wider and deeper tank then what it actually is and makes sense because the ocean is like that where its darker as it goes on
