20140137807 | FISH TANK FOR ALLOWING AQUARIUM FISH TO BE VIEWED CLEARLY FROM THE TOP - Hitherto, when viewing from above, it has been impossible to view aquarium fish clearly due to disturbances on the water surface. Provided is an improvement method, including a manufacturing method, that makes it possible to view aquarium fish clearly from above. Adopting a structure in which overflowing water flows into an upper gutter makes it possible to view aquarium fish clearly from above for long periods of time. | 05-22-2014 |
