Best Plants for Nano Planted Tanks (Under 10 Gallons)
By Maya Thornton . 9 min read . Updated June 2026
A nano planted tank under ten gallons can be one of the most rewarding aquascapes in the hobby, bringing a dense, lush garden into a small footprint on a desk or countertop. The key is matching your plant selection to your setup. Low-tech nano tanks with no CO2 do best with slow-growing, low-demand plants that will not outgrow the space quickly. High-tech nano tanks with a light like the ONF Flat Nano Plus LED and CO2 from the FZONE Aquarium CO2 Regulator Complete Kit or the Aquario Neo CO2 Diffuser (Standard) can grow demanding carpet species. Get the substrate right first with Fluval Plant and Shrimp Stratum (4.4 lb) or ADA Aqua Soil Amazonia (9L) and the plants will follow.
The short answer
Low-tech nano tanks do best with Anubias, Java fern, Bucephalandra, and Christmas moss, all of which grow slowly without CO2. For a carpeted high-tech nano scape, Monte Carlo, Micranthemum tweediei, and Hemianthus callitrichoides (HC Cuba) work in tanks as small as five gallons with CO2 injection and a light like the ONF Flat Nano Plus.

Low-light, no-CO2 plants for nano tanks
Anubias species are the most reliable low-tech nano plants. They grow attached to hardscape like Dragon Stone (Ohko Stone) Aquascape Rock or Spider Wood (Azalea Root) Driftwood , never need planting in substrate, and tolerate a wide range of lighting and water conditions. They grow slowly, which is an advantage in a small tank where fast growers become a trimming chore. Anubias nana petite and the coin-leaf Anubias are the best choices for a true nano where space is limited.
Bucephalandra is the Anubias alternative for hobbyists who want more color variation. Like Anubias, it attaches to hardscape, grows slowly, and tolerates low light. Buce produces tiny, delicate flowers underwater and comes in dozens of leaf shapes and colors.
Java fern is the simplest beginner plant: attach it to driftwood like Spider Wood (Azalea Root) Driftwood with thread or a dab of superglue gel, and it will grow in almost any water under almost any light. Do not plant it in substrate; the rhizome rots when buried.
Christmas moss attached to Dragon Stone (Ohko Stone) Aquascape Rock or a small piece of driftwood creates a soft, forest-floor texture for nano scapes. It is more demanding than Java moss but still manageable without CO2 under moderate light from a Hygger 24/7 LED Planted Aquarium Light .

High-tech carpet plants for nano aquascapes
The dense green carpet look of a competition aquascape is achievable in a nano tank with CO2 injection and sufficient light. The most popular carpet plants for small tanks are Monte Carlo (Micranthemum tweediei), HC Cuba (Hemianthus callitrichoides), and dwarf hair grass (Eleocharis parvula).
Monte Carlo is the most forgiving carpet plant for high-tech nano tanks. It grows relatively quickly under a light like the ONF Flat Nano Plus LED , spreads via runners across the substrate surface, and is slightly more tolerant of moderate rather than intense light compared to HC Cuba.
HC Cuba creates the finest, densest lawn texture but requires the highest light and CO2 of common carpet plants. In a nano tank shallower than eight inches, the Chihiros WRGB II Pro LED Aquarium Light on a small size or the ONF Flat Nano Plus LED can push sufficient PAR to the substrate. Use ADA Aqua Soil Amazonia (9L) for the best HC Cuba results.
For the substrate in a carpeted nano scape, use at least two inches of ADA Aqua Soil Amazonia (9L) or Fluval Plant and Shrimp Stratum (4.4 lb) . Use the Aquario Neo CO2 Diffuser (Standard) for in-tank CO2 delivery.
ONF Flat Nano Plus LED

Aquario Neo CO2 Diffuser (Standard)
Acrylic ceramic-disc diffuser producing ultra-fine CO2 mist for efficient dissolution, a favorite in the aquascaping community for its consistent microbubble output.

Aquascaping tools for nano tanks
Tool length matters in a small tank. Long 16-inch tweezers are awkward in a six-gallon tank. For nano aquascapes, a 10 to 12 inch straight tweezer and the Aquario Neo Spring Scissors (Curved) with their curved blade are the right combination.
For substrate shaping in a nano scape, the Tropica Substrate Spatula lets you build the characteristic sloped terrain. Nail the slope before you plant and you will thank yourself when the carpet fills in over four to six weeks.
A complete nano tool kit does not need to be expensive. The UNS Pro Aquascaping Tool Set (4-Piece) covers scissors, tweezers, and spatula in one purchase for around forty to fifty dollars and handles nano tanks comfortably.
Aquario Neo Spring Scissors (Curved)
Spring-loaded curved scissors that automatically open between cuts, reducing hand fatigue on extended trimming sessions and providing the finest precision cut in this price range.
$18-$30 budget
Tropica Substrate Spatula

$20-$35 budget
UNS Pro Aquascaping Tool Set (4-Piece)
Four-piece stainless aquascaping tool set including spring scissors, straight tweezers, curved tweezers, and a substrate spatula, the value-per-dollar benchmark for hobbyist aquascapers.

Fertilizing a nano planted tank
Nano tanks are sensitive to fertilizer overdose because the water volume is small. Use concentrated all-in-one fertilizers like APT Complete All-in-One Planted Tank Fertilizer or Seachem Flourish Comprehensive Supplement at a reduced dose, starting at half the recommended amount and increasing only if plants show deficiency symptoms like yellowing or stunted growth.
In a low-tech nano with slow-growing Anubias and Java fern, a once-weekly dose of Seachem Flourish Comprehensive Supplement after a water change is often all the fertilization needed.
APT Complete All-in-One Planted Tank Fertilizer
All-in-one liquid fertilizer formulated by the 2Hr Aquarist covering macros and micros in a single dose, designed for low-dose daily use in planted aquariums with or without CO2.

FAQ
Frequently asked questions
How do I keep algae out of a nano planted tank?+
Algae in nano tanks is almost always caused by an imbalance: too much light, not enough nutrients, or unstable CO2. Dial the photoperiod back to eight hours, ensure your fertilizer routine covers basic nutrients, and if you run CO2, keep the drop checker green. Avoid introducing algae on plants by soaking new plants in a diluted hydrogen peroxide solution before adding them.
Can cherry shrimp live in a planted nano tank?+
Yes, neocaridina cherry shrimp are ideal nano tank inhabitants. They eat algae, clean up plant debris and uneaten food, add color, and need only a sponge filter like the Aquarium Co-Op sponge filter for safe filtration. Avoid any copper-containing fertilizers or medications, use a copper-free water conditioner like Seachem Prime, and keep the water stable rather than chasing perfect parameters.
