I have a background that I bought as a generic tank background. It basically looks like a continuation of my aquarium.... many of the same plants, same gravel color, deep blue behind the plants. It is a lot less cheesy than the one on my stepdaughter's tank upstairs, which doesn't match the contents of her tank.I didn't bother trying to attach it to the tank. I just stuffed it in the space between the wall and the tank. My tank is on a built-in windowseat, and so only the front view is visible anyway. And yes, before anyone has Qs about the window part of the windowseat, the window is blocked to prevent direct sunlight from coming in.
