The fastest nutrient sponge you can buy. Lemna minor — Duckweed — is barely 2mm across but multiplies faster than almost any aquatic plant, forming a dense surface mat that shades algae out and strips nitrate and phosphate from the water as it goes. Ponds and heavily stocked tanks clear noticeably with it.

Grower’s Notes
- Understand what you're introducing. Duckweed is famously difficult to remove once established — a single frond left behind repopulates a tank. Add it deliberately for nutrient control or fish food, not casually as decoration.
- It is excellent food. Goldfish, koi, cichlids and many pond fish graze it, and it regrows faster than they can eat it.
- Surface flow packs it into corners where it rots. Aim filter returns downward or use a floating ring.
- Skim it back at every water change. Left unchecked it seals the surface and starves plants below of light.
- It sticks to wet hands, nets and buckets — the main way it spreads between tanks.
Notes
- Pictures are sample representations. Portion size and frond count vary naturally.
- Never release aquarium plants into natural waterways.

Customers praised the healthy, vibrant plants with "excellent packaging" and quick delivery. Many noted "plants are thriving" and fish/koi love them. However, some experienced die-off from sun exposure or insufficient quantity. Several requested instructions for acclimation and care. Overall, customers recommend for ponds and aquariums.
- Arrived so green and without any damage to the plant. 10/10 would recommend
- Arrived very nicely packed. The koi love duckweed as a treat.
- Plants are thriving & growing in a sunny window.

Arrived healthy but is melting a little, would probably purchase again!

Unfortunately most to all have died within days of being added to my pond. I gave more stars as the customer service was great when replacing the first order that the USPS folks lost.
M
It would have been nice to get some directions in how to introduce the duckweed to the pond. As it is very few of them lasted more than a week. They seemed to get too much sun exposure. I wasn't aware that they would need to be hardened before adding them. :*(
R
Ordered some duckweed, and they arrived not only earlier than expected. They also arrived so green and without any damage to the plant. 10/10 would recommend 👍
T
Arrived very nicely packed. The koi love duckweed as a treat. Would highly recommend this floaters for your pond or aquarium.
J
My aquarium arrived late so I received the plants before my aquarium got here. I put the duckweed in a bowl of water until then. My cat stepped on the bowl and duckweed went everywhere, but they all survived my cat's clumsiness. All of the other plants I bought also survived my cat.

Im not trying to complain, but it just wasnt enough for my 60 gallon tank. From reviews i figured one pack would be enough. Most of it is drying up on the sides or being eaten by minnows.
P
Ordered a small sample of duckweed and saw that there was a sale so bought two anubias congensis as well. So far the plants are doing well and add a much need vibrancy to my fish tank. The order arrived on time and was nicely packaged, will most likely be ordering again.
S
The duckweed came healthy and greeb but had a bunch of snails the grew on it
J
Plants are thriving & growing in a bowl in a sunny window. Should be able to harvest some in a week or so for the goldfish in the pond outside
B
Idk yet wish there were instructions on how to grow it.
N
I'm assuming it was how long shipping took but there was some that was browned when it arrived. It's thriving in my shrimp tank, bright green lol
A
The plants are good quality, and were packaged professionally. They are still alive and well after about a week.
J
Healthy and beautiful
G
The duckweed came in great condition and is doing great in the tank. I would definitely order again for here.
J
Great packaging! A lot for a small portion!
R
Multiplied really easy
H
All I needed was a floating ring to keep them in place, but other than that these plants are great! I have a betta and some ghost shrimp and they all spend a lot of time underneath: seems like the new hangout spot!
S
This is the first time I bought these plants and I have to say they are worth it! My snapping turtles and mollies love them, and I will consider getting more if I need to. They almost ate them all! Good thing I have the extra one free so I can grow them myself.
K
I am very satisfied with the duckweed I received. I would definitely recommend. It also was shipped very quickly.
D
Arrived quickly, and in great shape, very healthy plants! So healthy that my huge Oranda Gold fish devoured them before they even got started in the tank!! They want to know when the next feast will be here!
m
When will this duckweed be available again?
Please check back soon. It's a seasonal product.
