    Andy, the near-universal black background is usually, not always, an artifact of front-lighting with flash. If the tank has any depth (front-to-back, not top-to-bottom) and the flash is near the tank's front, anything toward the tank's rear can easily be a couple of stops down from what's at the front.

    The effect can also be obtained with top-lighting. In this case, what's not under the flash gets very little light. This can be useful for minimizing the ill effects of scratched glass.
