I have alway's considered my tank a Nano, and I have a 28 gallon bowfront.
I was a believer in the 24 inch limit, but apparently the latest craze in Nanos is the 20 long, which I belive is a 30 or 33 inch length.
I would post a pic, but I was member #2004 so I don't have acess to the photo album thingy
