Best Easy Aquarium Planters for Planted Tanks
As an Amazon Associate we earn from qualifying purchases.
An aquarium easy planter is a way to grow a plant on or above your tank without digging into the substrate. The product data used here holds two true planters: a set of two clear hanging plant holders from GLEFLE and a 1.4 gallon Penn-Plax tank with a planting pot built into the lid. Other items in the data, such as feeders and a stand, are not planters, so they are left out. Two options is a short list, which is why the page spends its time on how each one works, what fits where, and what the listings do not say.
Quick answer
- For a tank you already own, the GLEFLE hanging holders clip onto the glass edge, provided the glass is thinner than 0.8 inch (2 cm).
- For a new small setup, the Penn-Plax Aqua-Ponic tank is a 1.4 gallon round tank with a lid pot for a plant on top.
- Both listings name plants that suit them, but only the Penn-Plax lists specific ones.
- Ask a fish store before putting any plant or fish in a tank; the listings are not care guides.
Two kinds of easy planter
The word easy can mean two things. For a hanging cup, easy means no tools and no changes to the tank: you hook it over the rim and the plant sits at the water line. For an aqua-ponic tank, easy means the plant and the fish share one small system and you water the plant instead of managing a separate pot. The listings describe these two designs very differently, and the right choice depends on whether you are adding to a tank or starting one.
GLEFLE hanging aquarium plant holder, 2 pack (B0D146WNNP)
This set holds two clear acrylic cups, each 3.15 by 3.15 by 2.25 inches, weighing 1.48 ounces per piece (0.14 kg for the set as listed). The listing says each hangs on the glass edge of an aquarium, includes one adjustable screw, and fits glass thinner than 0.8 inch (2 cm). That limit is the first thing to check, since thick glass or a rim with a brace will not take the clip.
The bottom of each cup has holes. The listing says they help plant roots grow and water circulate, and says this can reduce how often you change water. Treat that as the seller’s claim: it is a general statement and the listing gives no numbers. The listing names aquatic plants and ferns, along with greenery, bamboo, lotus, daffodils and water poppies, and says you can grow any aquatic plant you like. That last phrase is broad and no source here confirms any single plant will thrive, so confirm plant choices with a fish store.
The listing also says the cup can offer fish a hidden place to swim and hide, and that it works in freshwater or saltwater. The material is plastic, the listing mentions acrylic, and it carries a lifetime warranty entry. Who is it for? Someone who has a tank and wants one or two plants at the surface, perhaps to add greenery near a window or to try a plant before committing to a larger planting. Who is it not for? Anyone with a thick glass rim or a lid that does not leave room at the edge. View on Amazon
Penn-Plax Aqua-Ponic planter and aquarium for betta fish (B072R16KX1)
This is a whole tank. It is round, plastic, 1.4 gallons, and the listing gives the product dimensions as 8 by 8 by 10 inches at 2 pounds, with a more detailed set of measurements: overall 7.75 inches in diameter and 10.25 inches high, a black base 1.75 inches high, a tank interior 7.25 inches high and an enclosed pot 3.75 inches across and 2.25 inches deep. The box holds the plastic tank, a lid with the enclosed pot and ceramic planting media.
The listing says the tank is made of ultra-clear plastic and is a hydroponic planter on top, with fish and plant in a symbiotic setup. For the plant, it says most indoor house plants and kitchen herbs are suitable, and names Peace Lily, Chinese Evergreen, Lucky Bamboo, English Ivy, Mint, Watercress, Chives and leafy lettuce. It recommends established plants rather than starting from seed. The ceramic media holds water and supports roots, and you add water by watering the plant as you would a potted plant. The listing also notes several side openings large enough to drop in a pinch of food.
For fish, the listing says bettas are the most popular, and that it can also house bloodfin tetras, white cloud minnows, danios and guppies, in a number of 1 to 3. For bettas it asks you to lower the water level by an inch so the fish has space to breathe from the surface. Be careful with that guidance: it is the seller’s advice for this specific tank, and a fish store or aquatic vet should confirm what suits your fish. The listing gives no filter, heater or light, and it states a warranty only as Amazon policy. View on Amazon
A close alternative: AQUASMITH 2 gallon all-in-one tank (B0F5HM6QJ3)
This is not a planter, and its title does not say planter, so it is offered only as a comparison for readers who want a small tank with the equipment already built in. The specifications list a “Self Watering” feature, but the bullets describe it as an all-in-one 2 gallon glass tank with silent filtration (bottom and rear filter, under 35 dB), a waterfall output and surface skimmer, and an adjustable flow of 180 L/H. The filter uses a high-density pad, activated carbon and bio-ceramic media, with expandable slots that the listing says can take a heater or air pump. It adds a patented water-change feature, a built-in LED light, a 12V low-voltage system and a feeding port, at 3.49 kg.
The listing does not mention a planting basket or plant holder, so you would still need a cup such as the GLEFLE set to grow anything at the surface, and you would need to confirm that the glass or lid allows it. The listing calls the tank suited to small fish like bettas. It is the better choice than the Penn-Plax if you want filtration included, and the weaker choice if the plant is the point.

Planning a small planted desk tank
A planter works best when the rest of the tank is already settled. Think in four steps. First, pick the tank and check its size against the space, remembering that the Penn-Plax is just over 10 inches tall with the lid pot, which matters under a shelf. Second, decide how the water will be kept clean. The Penn-Plax listing describes the plant and fish as a shared system, but gives no filter, while the AQUASMITH lists a three-part filter. Third, choose the plant to match the planter: the Penn-Plax listing names house plants and herbs, and the GLEFLE listing names aquatic plants and ferns. Fourth, decide who will care for it. The AQUASMITH listing pitches the tank for children learning pet care, which is a sales line and not a guarantee that a child can manage it alone.
Whichever route you take, change one thing at a time. If you add a plant cup, a new light and a new fish in the same week, you will not know which change caused a problem. Keep the plants trimmed back from the lid so the fish still has surface access, which the Penn-Plax listing flags when it asks you to lower the water level for bettas.

How to choose
Start from what you already own
If you already run a tank, measure the glass first. The GLEFLE clip only works under 0.8 inch, which covers most small home tanks but is worth confirming with a ruler. Then think about where a cup would sit: at the back corner it hides the fixture, while at the front it blocks the view. A cup at the surface also sits in your light path, so it may shade plants below.
Start from scratch
If you do not own a tank, the Penn-Plax gives you a single object to place. Its listing has no filter or heater, and a 1.4 gallon volume is small, so check what a fish store recommends for a betta tank of this size. Our page on aquarium decor options shows what else can go in a tank of this kind, and our canister filter guide covers filtration for larger tanks.
Match the plant to the tool
The two listings expect different plants. A hanging cup holds roots at the water line, so the plant choices are aquatic or marsh plants with roots that will sit in water. The Penn-Plax lid pot is a hydroponic planter, and the plants it lists are common house and herb plants. Mixing these up is the main way to waste money, so read the plant list in the listing before you buy.
What the listings do not say
Neither planter listing gives a weight limit for the plant and wet media, a recommended water depth for the hanging cup, or a list of plants confirmed safe for fish. The GLEFLE listing gives the cup size and glass limit but not the volume of soil or media it holds. The Penn-Plax listing gives full measurements but no light requirement for the plants it names, and it states no heater or filter. When a listing is silent, the safe move is to ask the seller or a fish store before buying, not to assume. Photos help too, since the clear cups and the round lid pot are easy to misjudge from a title alone.
Mistakes to avoid
- Skipping the glass thickness check on the hanging cups.
- Planting seed in the Penn-Plax pot. The listing recommends established plants.
- Leaving the fish without a plan for warmth and filtration; the Penn-Plax listing states neither.
- Treating the listing’s fish suggestions as a stocking plan. Ask a fish store.
- Putting a plant in the cup that cannot live with wet roots.
FAQ
What is an easy planter for an aquarium?
It is a holder or lid pot that lets a plant grow at or above the water without planting into the substrate. The two options here are a hanging cup and a tank with a planter lid.
Does the planter need special equipment?
The GLEFLE cups come with one adjustable screw each. The Penn-Plax comes with the tank, lid pot and ceramic media. Neither listing mentions lights or filters.
Can I use house plants?
The Penn-Plax listing names several house plants and herbs. For other plants, ask a fish store.
Is the Penn-Plax tank right for a betta?
The listing names bettas as the most popular fish and asks you to lower the water an inch. Confirm size and setup with a fish store or aquatic vet. See also a betta heater option.
What if my fish seem unwell?
Ask an aquatic vet. See signs of sick freshwater fish for what to watch.
Bottom line
Own a tank with thin glass: take the GLEFLE hanging cups. Starting a small desk setup: take the Penn-Plax tank, and plan your own warmth and filtration after asking a fish store.
