Best Nano Aquariums for Planted Tanks (2026)
Updated How we research
LANDEN 36N 5 Gallon Rimless Low Iron Nano Aquarium Tank
The LANDEN 36N 5 gallon rimless low iron nano, a scaper-favorite shell for shrimp tanks and compact nature layouts.
Ultum Nature Systems UNS 5N Ultra Clear Rimless Nano Aquarium 5 Gallon
The UNS 5N, a 5 gallon ultra clear rimless nano from Ultum Nature Systems, a step up in room for planted nano scapes.
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.

#1The LANDEN 36N 5 gallon rimless low iron nano, a scaper-favorite shell for shrimp tanks and compact nature layouts.
Fit for the job 9/10 · Features and specs 8/10 · Build and materials 9/10 · Value 8/10
- + The 5 gallon size is more stable than tiny nanos while still fitting on a desk
- + Low iron rimless glass is built with aquascape photography and display in mind
- + LANDEN sizes match many nano lights and accessories made for Japanese-style tanks
- - Bare tank, so a leveling mat, filter and light must be bought to finish the setup
- - Premium nano glass costs noticeably more than generic framed tanks of this size
#2The UNS 5N, a 5 gallon ultra clear rimless nano from Ultum Nature Systems, a step up in room for planted nano scapes.
Fit for the job 9/10 · Features and specs 8/10 · Build and materials 9/10 · Value 8/10
- + Extra depth over the 3N gives space for foreground carpets and background stems
- + Ultum's rimless glass and seams are made for display quality aquascapes
- + The 5 gallon size handles a small school of nano fish with better stability
- - Needs a nano light with enough spread to reach the corners of the longer tank
- - Filter and lid sold separately, which adds to the overall starting cost
#3A LAQUAL 3 gallon rimless nano in ultra clear low iron glass, an affordable start for shrimp and small plant scapes.
Fit for the job 8/10 · Features and specs 7/10 · Build and materials 7/10 · Value 9/10
- + Low iron glass at nano size makes tiny shrimp and mosses easy to see clearly
- + Rimless 3 gallon shape suits minimalist desk setups and small Wabi-Kusa style builds
- + Budget-friendly way to try aquascaping before committing to a larger tank
- - No filter or light included, so small nano equipment must be matched separately
- - Small water volume leaves little margin for overfeeding or skipped water changes
#4NICREW's 2.5 gallon nano kit pairs a high-clarity glass tank with a filter, light, lid and pre-glued leveling mat, a compact desktop base for a small planted scape.
Fit for the job 8/10 · Features and specs 8/10 · Build and materials 7/10 · Value 7/10
- + Listing states 91.2% light transmittance glass, which helps plants and hardscape read clearly through the front pane
- + Filter and light are included, along with a lid and a pre-glued leveling mat, so the tank is ready to set up out of the box
- + Comes with a step-by-step setup guide written for beginners, and the footprint suits desks and countertops
- - At 2.5 gallons the planting area is small, so layouts are limited to a few small plants and modest hardscape
- - Listing gives no wattage, spectrum or flow figures for the included light and filter, so their strength is unknown
#5An iPriro 3 gallon glass nano aquarium bundled with a filter and LED, for beginners who want a ready-to-run small tank.
Fit for the job 7/10 · Features and specs 7/10 · Build and materials 6/10 · Value 8/10
- + Included filter and LED remove the guesswork of matching nano equipment
- + The 3 gallon size suits a betta, shrimp colony or simple low-light plants
- + All-in-one package gets a first nano running with minimal extra shopping
- - Stock LED is likely too weak for demanding carpeting plants

#6AWXZOM's 1.1 gallon rimless clear glass tank, a very small nano for moss balls, a few shrimp or a desk plant display.
Fit for the job 6/10 · Features and specs 6/10 · Build and materials 6/10 · Value 8/10
- + Tiny 1.1 gallon footprint fits on a crowded desk or windowsill shelf
- + Rimless clear glass keeps the look clean for a miniature planted layout
- + Low commitment option for testing hardscape ideas before scaling up
- - Too small for most fish, so it suits plants, snails or a few shrimp only
- - Low iron glass shows scratches clearly, so clean it with a soft pad
#7Aquatop's Pisces bullet shaped glass nano kit, a decorative small tank for a betta or simple plant display.
Fit for the job 6/10 · Features and specs 6/10 · Build and materials 7/10 · Value 7/10
- + Rounded bullet shape gives a modern, eye-catching look on a shelf or counter
- + Kit format includes the basics needed to get a small tank running
