At just 4.5 inches thick, the Aqua Vista 500 is perfect for people who don’t want the clutter of a large tank. Essentially a flat screened aquarium, the tank has some impressive features. An advanced pump and filter system helps to keep the unit clean and an embedded LCD panel with built in thermostats will keep your fishies comfy. And the user friendly controls allow you to monitor and maintain the tank with little effort. The most obvious benefit however is its space saving design. However, were not sure how your fish will feel about living in such cramped quarters.
