Best Aquarium Plant Holders and Stands
As an Amazon Associate we earn from qualifying purchases.
An aquarium plant holder is a small cup or basket that hangs on the tank rim or sticks to the glass, so a plant’s roots can sit in the tank water while the leaves stay above or beside it. The eight listings below differ mainly in how they mount (hook, clamp, suction cup), how deep they are, and how many holes they have. Check the glass thickness your tank has against the listing first, because that decides which holders will fit.
Quick answer
- Thin glass (under 0.8 inch / 2 cm): the GLEFLE clear acrylic holders list that limit.
- Thicker glass or rimless tanks: the Borlech holders and the 2-pack with suction cups list hooks up to 1.57 inches plus suction cups.
- Deepest cup: the 2-pack with a 3.94-inch deep planter keeps roots submerged in low water, according to its listing.
- Not a plant cup at all: the AccEncyc suction clips hold veggies, seaweed and artificial plants.
What to check before you buy
Glass thickness and mounting
Every hang-on holder has a maximum glass thickness. The GLEFLE listing says it suits aquariums with glass thinner than 0.8 inch (2 cm). The Borlech listings say they hang on edges thinner than 1.57 inches (4 cm), or attach with suction cups for rimmed and rimless tanks. The 2-pack with suction cups lists three hook sizes (0.4, 0.8 and 1.57 inches) and says it installs on glass up to 1.57 inches thick. Measure your rim, then compare.
Depth and water level
A plant cup works because the roots sit in water. A shallow cup in a tank with a low water level can leave roots dry. One listing addresses this directly with a 3.94-inch deep planter, described as solving low-water issues for plants such as pothos and bamboo. Other listings give a smaller height, for example 2.25 inches for the GLEFLE and 2.56 inches for the Aidmi.
Holes and water flow
Most of the listings describe holes or slits at the bottom for root growth and water circulation. Several claim this helps the biological cycle and reduces the frequency of water changes. Treat those as seller claims: a plant cup is not a replacement for a filter or a maintenance schedule, and our guide to aquarium plants for a betta tank covers what actually goes in the water.
Material
The materials stated are clear acrylic (GLEFLE; the spec table says plastic), polypropylene or PP plastic (Borlech), ABS plastic (the 3-hole cup) and plastic (the others). The Borlech listings describe PP as corrosion resistant, high temperature resistant and non-toxic. Whichever you choose, rinse it before use.

The eight listings
GLEFLE 2 PCS Clear Acrylic Aquarium Plant Holder
The listing describes clear acrylic holders that hang over the glass edge, with a size of 3.15 x 3.15 x 2.25 inches, one adjustable screw and a single weight of 1.48 ounces. The compatibility note is clear: glass thickness under 0.8 inch (2 cm). It mentions holes at the bottom for roots and water circulation and suggests aquatic plants, ferns, bamboo, lotus and other greenery. It also states a lifetime warranty in the spec table. Good for a standard thin-glass tank where you want the clear look. View on Amazon
Aidmi 2PC 7 Holes Hanging Aquatic Plant Cup with Long Hook
This pair is 5.12 x 1.81 x 2.56 inches and weighs 4 ounces, with a long hook that the listing says lets it hang on various types of aquariums. It lists seven holes for root growth and mentions pothos as an example of a plant that can thrive with roots in the tank water. The spec table lists a drainage hole and a 1-gallon tank volume, which is a spec entry rather than a requirement. Suits someone who wants a hook design with plenty of holes. View on Amazon
Borlech Large Aquarium Plant Holder with Extension Hooks (2 count)
The listing describes a large holder made of PP plastic, with slits and holes for water flow through the roots. It has two uses: hanging on the edge of aquariums (thickness less than 1.57 inches / 4 cm) or attaching to the glass with suction cups, for rimmed and rimless tanks. The item weight is listed as 31 g for the pair. Pick this if you are not sure of your rim type and want both options. View on Amazon
Borlech Large Aquarium Plant Holder, second listing
A closely related listing with the size given as 3.5 x 3.5 x 3.94 inches. It lists six hooks, two of each size (0.4, 0.8 and 1.57 inches), plus two suction cups of 1.18 x 0.43 inches, and a product weight of 1.1 ounces. The same PP material description applies. The listing explicitly notes it suits rimmed and rimless tanks. View on Amazon
AccEncyc 12 Pcs Veggie Clips (a close alternative, not a cup)
These are suction-cup clips for holding leaves, sea veggies, seaweed and dried leaves, with a 1.85-inch suction cup diameter. The listing also says they can hold a betta bed, artificial plants or decorations. They do not hold a potted plant, so consider them as a different tool. The listing suggests soaking a deformed sucker in hot water for 60 seconds, and states a 6-month warranty. View on Amazon
3 Holes Upgraded Aquatic Plant Cup (2 count)
This is a clamp-style holder in ABS plastic. The listing says the plant goes through the hole without additional fixation, that the clamp keeps plants from accidentally falling in, and that each cup has three holes for plants such as pothos and daffodils. The pack is described as 2.55 x 1.77 x 2.36 inches. Suitable if you want something compact and clamp fixed. View on Amazon
2PC 7 Holes Upgraded Aquarium Plant Holder
Another hook-style pair with seven holes and a stated size of 5.12 x 1.81 x 2.56 inches. The listing mentions ferns, bamboo, lotus, daffodils and water poppies as suitable plants, and says it is made of high-quality plastic. It is very close to the Aidmi listing in its description. View on Amazon
2 Pack Aquarium Plant Holder with Suction Cup and Extension Hook
This one lists a 3.94-inch deep planter, a multi-hole design and two mounting options. It includes 2 plant holders, 4 suction cups and 12 hooks. The hook sizes are 0.4, 0.8 and 1.57 inches, and the listing says it installs on glass up to 1.57 inches thick and is compatible with rimmed and rimless tanks. If you worry about roots drying in low water, the depth is the main reason to choose it. View on Amazon
Picking by situation
Thin glass, standard tank
The GLEFLE, with a stated 0.8-inch limit, is the simplest match, as long as your glass is thinner than that.
Thick glass or a rimless tank
The two Borlech listings and the 2-pack with suction cups state hooks up to 1.57 inches and suction-cup mounting, so they cover more situations.
Low water level
The 3.94-inch depth of the 2-pack makes it the one to check first, along with the Borlech at 3.94 inches high.
Heavier plants
The listings do not state a load limit, so keep plants light and check the holder after planting. Plants with dense leaves can be top heavy.
If your tank has a sand base, our articles on plants for sand substrate and plants that do well in sand cover the plants that stay in the substrate, while a holder suits rooted floaters and pothos. For light, see freshwater LED grow lights, and for a different plant option, the plants for shrimp tanks article.
Setting up a hanging plant cup
The listings agree on the basic idea, even where they differ on hardware. The cup sits at the edge of the tank, the plant stem passes through a hole or the open top, and the roots hang down into the water through the holes at the bottom. A few practical steps follow from that:
- Measure the glass or rim where the holder will sit, and compare it with the maximum in the listing.
- Choose the hook size that matches (the multi-hook sets list 0.4, 0.8 and 1.57 inches), or use the suction cups on glass.
- Place the plant so that the roots reach the water but the leaves stay clear of it, since the listings describe the roots as the part that sits in the tank.
- Check the cup again after a day to make sure it has not slipped.
The listings name pothos, ferns, bamboo, lotus, daffodils and water poppies as examples. None of them gives care instructions for those plants, so check a plant guide for light and temperature needs before you commit.
Why people choose holders over planting in the substrate
A holder keeps the plant above the gravel or sand, so you do not have to disturb the base of the tank to move or remove it. That is a practical point for a small betta tank, where rearranging decor is part of normal care. The Aidmi and Borlech listings also describe the holder as hidden habitat or visual decoration, but the pack does not support any claim about specific water-quality benefits beyond what the sellers state, so we leave those as seller claims.
Mistakes to avoid
- Not measuring the glass. The limits range from 0.8 inch to 1.57 inches.
- Assuming a cup is a filter. The listings say they support circulation and root growth; they do not replace maintenance.
- Letting roots dry out. Check the water level against the depth of the cup.
- Buying clips for a cup job. The AccEncyc clips hold food and decor.
FAQ
What is an aquarium plant holder used for?
The listings describe growing aquatic or semi-aquatic plants with roots in the tank water, for example pothos, ferns, bamboo or lotus.
Will it fit my tank?
Compare your glass thickness with the stated limits: under 0.8 inch for the GLEFLE, up to 1.57 inches for the Borlech and the 2-pack.
Do I need suction cups?
They are an alternative to hanging, listed on the Borlech and the 2-pack, for rimmed and rimless tanks.
Are the materials safe for fish?
The listings describe their plastics as non-toxic and safe. These are seller statements; if you have concerns, ask a vet or the manufacturer.
How many holes do I need?
The listings do not give a rule. Seven holes are listed for two models and three for another, and more holes give roots more room to pass through.
Bottom line
Match the holder to your glass thickness first, then to your water level. For thin glass, the GLEFLE; for thick glass or rimless tanks, a Borlech or the deep 2-pack with suction cups.
