seems like food,poop, and other junk would always be visible and get easily stirred around, but my walmart uses bare tanks
when i switched from a 10 to a 55gal i didnt have enough gravel so i put all the gravel on one side of the tank, inorder to anchor my plants, and left the other half bare till i could get more gravel. while my tank was setup like this the fish never swam over the bare glass
