I agree backgrounds totally change the look. I even used a black garbage bag behind one tank until I got a regular background. For another inexpensive option try a vinyl tablecloth for like 2$. I got great deals on eBay on regular background. Attached with double sided tape I've seen some nice painted backgrounds too ( solid color)
