# Best Nano Aquariums for Planted Tanks (2026) Source: https://aquascapenest.com/best/nano-aquariums Updated: 2026-10-06 Publisher: Aquascape Nest. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://aquascapenest.com/how-we-research#our-score Nano aquariums pack an entire aquascape into a tank you can set on a desk or shelf, usually under about 10 gallons. When you are choosing one for a planted setup, focus on glass clarity, a shape that gives you room to place hardscape and plant carpets, and an open top that makes it easy to run a light and trim stems. Rimless designs look cleaner, but braced tanks can be more forgiving if you plan to move the tank or stack heavy rock. A nano tank suits anyone who wants a low-cost, low-space way into aquascaping, or a second display for a small collection of shrimp and slow-growing plants. Keep in mind that smaller water volumes swing faster in temperature and water chemistry, so they reward steady maintenance over neglect. If you enjoy detailed, hands-on scaping and do not need large fish, a nano is a great starting point. ## Picks ### 1.
