Spray painting it black normally works pretty good. Brings out the colors of your fish better, gives you tank more depth, just makes it look great. Thats why I did on my 125gal and 20gal. Watch out for runs though! Do several light coats.

if you dont want to paint it, i would just leave it alone. i like the pipings and tubing to be visible LOL. dont use cloth or sheets, it kinda looks cheap

If you don't want to paint, they sell foam poster boards that look pretty nice. I'd go black, but if you want another color, I'd say red would go with the gravel and your wall color.

Grow an algae wall, looks good, free and food for fish.
I have a partly finished one on my grow out tank

and to think, I just cleaned a lot of algae off the back wall of my tank...

I'm sure it absorbs CO2, produces oxygen, absorbs nitrogen, and its great if you forget to feed your fish. and less cleaning...



and a couple of snails would keep it from getting too out of control, while mowing trippy trails through it!
