20g - tank background recommendation?
I'm planning a 20g (24"x12"x16") aquarium and need background recommendations. I'm leaning towards pure black, since I've done blue before (and my substrate will be Flourite black).
I am not going to paint a background on the tank, so that is out of the question.
I was also thinking a rocky background, as long as there aren't any plants, just to give some variation when looking at the tank.
