From my last 180g saltwater reef tank for many many years, I've graduated up to a 5 gallon fresh planted tank for next to my kitchen counter computer I use for hours a day.
Just got it wet a couple days ago, bought a couple handfuls of 5-7 species of plants from a guy on Craigslist, and shopping for planting substrate and fish soon.
Guy had a fishroom just like in the video but only ~25-30 tanks where he breeds angels and shrimp to sell.
Going to have fun with this one. Heck, a 20% water change is only a gallon of water. I think I can handle that.
Goal is a Lite Bio-load and little feeding with lots of plants should almost be a closed eco-system that self maintains itself.
5 gallon size is a perfect countertop unit at only a 8x16" footprint and 10" tall. LED lighting is cheap and super bright.

You can always build a double sided tank into your house wall so it doubles as a Window too.............
