The Sea-Quarium is of the highest quality! The tank is injection molded in one piece and has 5 magnifying portals on the front curved pane. The hinged lid holds the LED Light Unit (included in the Deluxe Edition) in place, has vents, and can accommodate an airline for our Hydro-Pump (also included in the Deluxe Edition)! It also has a timer! This is the perfect container to grow and watch all kinds of aquatic life develop!
