We are purchasing a tank and a stand. The stands are secondhand and slightly larger than the tank. There is lots of information about not overhanging a tank on a stand, but can a tank be smaller than the stand? Or photographs of stand with tanks on have the tank sitting on the outer edge, and I assume this is to utilise the strength of the side panels on the stand. However, would it be disastrous to have it a bit smaller than the tank stand? In my case the width of the tank is 61 cm and the width of the stand is 81 cm. Thank you.
