I was just considering setting up a pico tank when I wondered, is there actually a definition of what makes a planted tank a nano or a pico?
I've seen a couple of discussions that say that a planted nano is anything under 10USG (~40l) some prefer to use size rather than volume say under 20" width and that a pico is anything under 2USG (7.5l).
While I was looking around the site there were photos of 'scapes in glasses and even one in a CD spindle lid. These don't tend to have filtration but instead rely on frequent water changes... could these be femto tanks?
