The Fluval Edge is a 6 gallon/23 Liter glass aquarium that brings cutting edge style and design to the “nano” tank category. Considering its size, this aquarium was designed with the advanced hobbyist in mind; however, through proper education, the Fluval Edge is not beyond the grasp of a relatively novice fish-keeper. Understanding the basic limitations of small aquariums is important for success with a Fluval Edge aquarium. More on this later…
Most people are excited and intrigued by one of the most unique aspects of the Edge’s design: the glass top. The raised opening of the glass top sits hidden under the canopy and allows for the water level to hide above the viewing area of the tank. This creates a clean and modern floating “water cube” effect devoid of traditional rims.
But while the visuals speak for themselves, how about a look under the hood?

Also of note, the top of the canopy contains many small holes to allow warm air to escape that is generated while the lights are turned on.

Recommended Stocking and Use: It is extremely important to consider proper use and animal husbandry when considering any small “nano” aquarium.
There are two keys to properly stocking a Fluval Edge aquarium:
1) Choose appropriate species of fish that will both stay small and be comfortable in a relatively small environment.
2) Don’t overstock! While the Edge filter contains enough biological and chemical filtration to filter an aquarium twice or three times its size, resist the temptation to put too many fish in the tank. Five or six small species should be able to coexist happily in most cases.
