The spherical shaped fish bowl is actually banned in several countries for this reason. Because of the shape, light that enters the bowl on certain angles bounces every which way, illuminating the whole bowl from every side. This is very disorienting, espescially for fish like guppies who orient themselves based on where the light is. If you put your strip light against the side of a guppy tank they will start swimming sideways!
