there already is a black background.FanOFish said:All the makings of a great looking tank are there. IMHO I would probably get rid of some of the rocks and make the driftwood the focal point of the tank.
Unless you are going to have a cichlid tank you really don't need so many rocks. Try making the wood the focal point and using the rocks to fill in....but not so much on top of each other, more like leaning into each other and then add some silk plants for color and depth. Finally add a dark blue or black background to kind of hide the equipment.
Good luck
the rocks have lots of cave space for the loaches which I plan to basically be the primary focus of the tank.
we'll see again once I've got the plants in the tank.
