I'm not so sure. I thought about making the entire cabinet larger than the tank in order to have space on the sides of the tank. This is exactly what the "shelf" would do for me. Only problem is that if you put anything on that shelf then it is covering up part of the tank and just becomes a distraction.
Taking my last idea from above, you get this. I could add panel D just to bring some relief into the side.
