Best Aquarium Planters for Small Tanks and Setups
As an Amazon Associate we earn from qualifying purchases.
A planter aquarium is a fish tank with a place to grow a plant on top or on the glass, so the plant roots reach the tank water while the leaves stay in the air or above the surface. The four listings below cover the main versions: two complete tanks with a planting area built in, and two add-on planters that attach to a tank you already own. All facts come from the listing text, and where a listing is silent we say so.
Quick answer
- For a complete small tank with a planter on top, the Penn-Plax Aqua-Ponic is a 1.4 gallon round tank and the LIYAOLI is a 2.5 gallon TV-shaped kit.
- For an add-on planter that hangs on the glass rim, the GLEFLE 2-pack fits glass under 0.8 inch.
- For a planter that sticks to the glass wall, the Aquarium Choice glass pot set uses dual suction cups.
- Two crystal gravel listings in our data were left out because they are sold as decorative stones, not planter products.
How to choose a planter aquarium
Complete tank or add-on?
A complete tank gives you everything in one purchase: the container, the planting area and, in some cases, a filter and light. An add-on planter costs you nothing in tank space but needs a tank whose rim or glass suits it. If you already own a tank, an add-on is the simpler path. If you are starting from nothing, one of the kits removes several buying decisions.
Check the size of the tank for your fish
A planter aquarium is usually small, and small tanks limit the fish you can keep. Our guide to what size aquarium for a betta fish covers the sizing question in detail. Read each listing’s own statement about suitable fish; some name bettas, some list other species, and some say nothing about fish at all.
What the plant needs
The listings differ on what you can grow. One lists house plants and kitchen herbs, one lists pothos or bamboo, others list aquatic plants, ferns and lotus. Each plant has its own needs for light and water, which a listing cannot cover, so match the plant to your light before buying.
Glass thickness and mounting
Hanging holders state a maximum glass thickness. Suction cup pots need a smooth glass wall. Both are easy to overlook until the product arrives.

The four listings
Penn-Plax Aqua-Ponic planter and aquarium
This is the most self-contained option in the group. The listing describes ultra-clear plastic tank walls and a design that “replicates nature’s metabolic cycle,” a seller description of the hydroponic idea: the fish live in the tank and the plant sits on top. The tank is the brand’s 1.4 gallon Aqua-Ponic model.
On fish, the listing says bettas are the most popular choice for this tank, and that it can also house bloodfin tetras, white cloud minnows, danios and guppies, one to three fish. For bettas, the listing says to decrease the water level, though the text we hold is cut short and does not give the amount, so read the full listing before filling it.
On plants, the listing suggests most indoor house plants and kitchen herbs, including peace lily, Chinese evergreen, lucky bamboo, English ivy, mint, watercress, chives or any leafy lettuce. The tank comes with ceramic planting media that retains water and supports root growth, and the listing says to add water by watering the plant as if it were in a pot of soil.
Measurements from the listing: overall 7.75 inches in diameter by 10.25 inches high; the black base is 7.75 by 1.75 inches; the tank interior is 7.75 by 7.25 inches; the enclosed pot is 3.75 inches across and 2.25 inches high. The spec rows give plastic material, a round shape, a weight of 2 pounds and included components of a plastic tank, a lid with enclosed pot, and ceramic planting media. The listing does not mention a filter or heater, so assume you need to supply your own if the fish you keep requires them.
Why it fits: it is the clearest example of the planter-on-top concept. Because the tank interior is 7.25 inches tall, it suits very small fish only, and our betta tank size guide is worth reading before you commit.
LIYAOLI 2.5 gallon retro TV fish tank kit
This kit is shaped like a television and sized at 30 x 20 x 20 cm, which the listing calls a 2.5 gallon aquarium for a desk or office. It includes a tank, LED lid, filter and plant basket. The lighting has three adjustable settings: calming blue, vibrant white and natural daylight modes. The listing describes a silent pump with mechanical filtration.
The planter is a built-in box for hydroponic growth. The listing gives pothos or bamboo as examples and says the plants naturally filter and add oxygen, extending water change cycles to 2 to 3 weeks. That is a seller claim and the listing does not provide supporting detail, so we would not rely on it as a schedule. It lists suitable animals as small tropical fish such as peacock fish and fighting fish, cold water fish such as goldfish, or small aquatic plants. Goldfish and fighting fish have very different needs, so the claim reads as general marketing; pick fish based on a proper care guide.
The spec rows list ABS material, a transparent special feature, a black 2.5 gallon color, filter and light as included components, and four items. The listing does not state a filter flow rate, which matters for bettas; see our aquarium decor comparison for ideas on filling a small tank without crowding it.
Why it fits: it bundles a light, filter and planter box in a single kit, so it is the more complete answer for someone starting a first small tank with a planter.
GLEFLE aquarium plant holder, 2 pieces
These are add-on cups that hang from the tank rim. The listing says they are made of high-quality acrylic with a smooth surface, though the spec rows list the material as plastic. Each measures 3.15 x 3.15 x 2.25 inches and the listing’s compatibility note says the glass must be less than 0.8 inch (2 cm) thick. The weight row gives 0.14 kg.
The bottom has holes, which the listing says helps plant roots grow and creates water circulation in the tank. Suggested plants include aquatic plants, ferns, potted plants, greenery, bamboo, lotus, daffodils and water poppies. We would treat that list as the seller’s suggestions, not a care guide, and cross-check any plant before putting its roots in a fish tank.
Why it fits: if you already own a tank, a rim-hung cup is the lightest-touch way to add a planter. The set of two lets you try one on each end.
Aquarium Choice glass aquarium plant pot, 4 pieces
This set is aimed at betta keepers in the listing: the title describes a betta resting bed spot. The listing’s contents are a glass plant pot, 100 colorful small stones, 12 large transparent stones, a long clip and a short tweezer, with the title naming four pots. A different bullet in the same listing gives 50 pebbles and six large transparent stones, so the counts are inconsistent; check the product page before you order.
Each pot is made of thickened clear glass that the listing calls non-toxic, and carries two suction cups to attach to the smooth glass wall. A small hole at the bottom allows water circulation and nutrient flow to the roots. The listing says the pebbles and stones can weigh plant roots down. The spec rows list glass, transparent, round.
The listing does not give the pot dimensions, the weight it can hold or the water depth it needs, so you will want to look at the product images for scale.
Why it fits: it mounts on the glass rather than the rim, so it works in tanks where a rim hanger would not fit.
Listings we left out
Two listings in our data are 7 to 9 mm tumbled crystal stones, including fluorite, sold in a 0.44 lb bag and a 1 lb bag. The text sells them as healing crystals and decorative stones, and mentions aquarium gravel only as one of several uses. They are not planter products, and the listing does not state that they are fish-safe, so we do not include them as recommendations.
Which one for which setup
You want a ready-made desk tank
Choose between the two kits. The Penn-Plax is smaller at 1.4 gallons and states its dimensions in detail but not its filter. The LIYAOLI is 2.5 gallons and includes a filter and light. If you plan to keep a betta, the larger volume is the better start, and our automatic fish feeder post may help with feeding when you travel.
You already have a tank
Pick the rim holder if your glass is under 0.8 inch thick, or the suction pot if you want something on the wall. The suction version keeps the rim free for a lid or hood.
You want to grow herbs or house plants
Only the Penn-Plax and LIYAOLI listings name house plants or herbs. The two add-ons mention aquatic plants, ferns and similar.
Mistakes to avoid
- Choosing a tank by looks and ignoring the fish. Small volumes limit what you can keep.
- Assuming a plant cleans the water enough to skip water changes. The listing claims are marketing, not a schedule.
- Ignoring glass thickness for hanging cups.
- Filling a 7.25 inch tall interior with tall decor.
- Planting something toxic or unsuited. Check any plant before use.
FAQ
Can a betta live in the Penn-Plax Aqua-Ponic tank?
The listing names bettas as the most popular fish for it, and tells you to lower the water level for bettas. Check our guide on betta tank size to decide whether 1.4 gallons suits you.
Does a planter on top replace the filter?
The listings do not say so. The LIYAOLI listing includes a filter, and the Penn-Plax listing does not mention one.
Which planter works on thick glass?
The GLEFLE holder states a limit of 0.8 inch. The suction cup pot attaches to a smooth glass wall, and its listing does not state a thickness limit.
Are the crystal stones safe in a tank?
The listings do not say so, and they are marketed as decorative crystals, so we left them out.
What plants can go in a planter?
Each listing has its own list, from herbs to lotus. Verify any plant’s needs before buying.
What if my fish looks sick?
Ask a vet who treats fish. See signs of sick freshwater aquarium fish for what to watch for.
Bottom line
If you want one purchase that gives you the tank and the planter, choose between the Penn-Plax and the LIYAOLI by tank volume and what is included. If you already own a tank, choose the GLEFLE holder or the Aquarium Choice suction pot by how your glass is built.
