I was debating this as well.... I am setting up my new tank and couldn't decide. so I went to my LFS still not knowing which color. and what do I find???? the background is black on one side and blue on the other! score! still cycling and will be putting my silver in soon. I can let you know in a week. unless you find out sooner. (I went with black right now, we will see if I change my mind)
