Not the lowest price ever, but I think this is a nice deal for a glass all in one aquarium. They claim FS at $49.
The Marineland 5 Gallon Portrait Kit is a five gallon curved glass aquarium. The kit features Marineland 3-stage hidden filtration with a Rite-Size Z Cartridge and Marineland Bio-Foam (included in the kit), and includes an adjustable flow filter pump. The bright white and blue energy-efficient LED light is hinged for easy access to the tank, and features a 3-way switch (toggle between white and blue, off, and blue-only settings). The white LEDs create a shimmering light in the water that mimic the underwater effect of sunlight, and the blue LEDs produce a relaxing moonlight glow. Also, included is a base and a unique glass canopy that slides to the back of the aquarium for easy feeding and water care dosing. This easy-to-assemble kit is beautifully designed and easy to maintain.
