This cube sparkles like a diamond, but costs a lot less. Light catches and refracts from the crystal clear sides of the Uniquarium Cube, creating a living work of art to show off your fresh or salt water fish. Get a big one, or one small enough for your desktop. Beginners love the everything-included simplicity, while pros appreciate the high-capacity Bio-Fil 3-way filter, Rio high-flow powerhead and more, maintaining perfect environmental peace without ugly tubes, pumps, or hoses. Choose your size and favorite tint color. Then just add water.
