I have a 72 gal bow-front tank. I had a black background which I was tired of, so I turned it around to the blue side and I hate it. I've been trying to find an online site with something nice, appropriate for a Malawi tank. I love the 3D ones that insert into the tank but don't want to spend that kind of money right now. Does anyone know of a place with a good selection? It seems everyone has the same basic stuff.
