Abstract: A substantially transparent separator for separating fish or other aquatic animals within a water-filled display tank is disclosed. The separator divides the tank into multiple, fully viewable regions in fluid communication with each other. The separator comprises at least one transparent, hollow transit chamber, which has opposing mouth openings cut through its surface. Affixed to each of the mouth openings are rigid, substantially vertical divider plates. Apertures through the divider plates adjoin the mouth openings of the transit chamber(s) to form a protected aquatic passageway through the interior of the tank. The separator thus allows groups of physically separated fish or other aquatic animals to swim above, beneath, and beside each other in a three-dimensional manner. Also, each group of aquatic animals has access to the water surface for feeding.
