A personal choice. I painted mine black (though I had doubts painting a perfectly new aquarium). I have yet to add fish due to cycling though so I'm not sure if it will indeed make the fish standout and feel more secure. The plants do look great against a dark background.
Backgrounds are only cosmetics........I have seen 3-D backgrounds made out of stirofoam.......My 125 is fitted with a black HEFTY garbage bag background.........
