what would be a good aquarium background for a tank with plants and black sand? either black construction paper, a diy 3d background, or a frost paint is what i was thinking. is there anyway to keep a diy background in place without the use of silicone?
I agree with J double R, make like the Rolling Stones and Paint It Black. But since you already have the tank filled, just use a plastic backgroundand if you can, use pam to spray the back first so the background looks darker.
