I have noticed that the front and back sides of the aquarium are bowing outward. It's a glass 20 tall, 24x12x16 (LxWxH), made by perfecto. I have never noticed this before, but the last time I used it was 5 years ago, so I wouldn't remember. The warping is just under 1/4 inch at the very center of the aquarium.
Is this just normal wear for older aquariums? I know larger aquariums are prone to this stress b/c of the long length, and they have a bar running across the top rim between the front and backsides so not too break. However, this is a relatively small aquarium and I'm sure should not be bending under stress. Wrong?
