What Are the Differences Between Frogbit and Duckweed?

The main difference between Frogbit and Duckweed is that Duckweed is hard to manage but is adaptable to different settings while Frogbit is a low maintenance option.

They are both effective tank cleaners that need constant trimming.

What Is Frogbit Best for?

The Frogbit is best for home aquariums because it’s so easy to care for, adds color to the tank, and cleans it of chemicals.

What Is Frogbit?

The Frogbit is a plant that has an ornamental nature, making it popular with aquarists who want to see this pretty little gem on their tanks’ shelves. It is native to the Central and South American regions, but there are reports of its existence in North America as invasive species. The Amazon Frogbit is a plant that you’ll find in both ponds and aquariums.

In the early stage, Frogbit grows flat leaves that are visible on the surface of the water. But as the plant ages, it will produce leaves that can rise above the water’s surface. Frogbit has small white flowers, and that makes it very attractive. A Frogbit in an aquarium can grow to a maximum of 20 inches and spread leaves across the entire surface.

What Is Duckweed Best for?

Duckweed is best as both food and shelter to many animals that live underwater, like fish or turtles. For nutrient growth control, they are added to the tank, but fast growth can sometimes lead to depleted parameters.

What Is Duckweed?

Duckweed is an essential plant for ponds and lakes that are used as a way to remove excess nutrients from waterways. This plant has been used for livestock feed and fertilizer production, but some people think it can be harming our environment because these manufactured products are taking over natural habitats where other plants live too.

Duckweed is a plant found on almost every continent in slow-moving lakes, rivers, and pond systems. This aquatic herb usually appears to be algae if you don’t know what you’re looking at because it grows large mats on top of the water’s surface with small leaves. It’s been reported as a nonnative species throughout Australia and South America, where pesticides have been used against them.

Frogbit Vs Duckweed: Similarities and Differences

In this section, you can find a detailed comparison between Frogbit and Duckweed, so that you can learn about their similarities and differences!


A Duckweed plant is a floating freshwater aquatic herb with 1 to 4 leaves, and it has a single root that is 0.5 to 0.8 inches in size. The plant can split up and result in oval-shaped leaves that further grow into individual plants. In an aquarium, they can grow up to almost 20 inches in size.

A gorgeous plant with intricate leaves and flowers, the Frogbit is a floating ornamental that produces flowers about 13mm in size. The glossy unmarked green shades of these plants make them stand out among other freshwater species.

At first glance, the common Duckweed plant may not seem particularly interesting. It has up to four leaves per individual and almost always only one root hanging from center stage. These small green oval-shaped leaves are usually barely a few millimeters long and wide. The flowers of these plants are too small for us even to see.


Frogbit is an elegant, low-maintenance plant for your tank. It can thrive in any size tank, and it’s very attractive to look at because of its bright colors that change with the seasons.

While if you look at Duckweed care, they are very difficult to manage. Many people who have grown Duckweed in their aquarium say that they aren’t low maintenance at all. The plant is likely to grow and cover your whole tank within a few days.

Furthermore, it tends to get caught up in filter intakes and power heads, which makes removing them difficult when they get stuck there. This additional maintenance may not seem like much if you plan to add this type of aquarium inhabitant.

On the other hand, Frogbit is not much different at all. It can also grow over the whole tank surface, leading to oxygen depletion. However, the key to growing healthy Frogbit is keeping the upper portion of their leaves dry because it can lead them to rot if they get wet.


Duckweed on the water surfaceDuckweed can adapt to different settings. They have the potential for success in any waterway, even if it’s somewhere, they’ve never been before. Similarly, the Frogbit is a hardy plant that can thrive in the wild and do well even when living with other plants. In tanks, too, it’s resilient enough to grow happily on its own or as part of mixed-species setups.

The rapid growth of the plants causes them to consume a lot of ammonia and nitrates, which in turn cleans up any excess nutrients from the water. Most species want their home to be freshwater with calm moving waters for optimum performance.

Nitrate Cleaning

People choose to have Duckweed when they want their aquariums clean and clear. It can absorb harmful nitrates; remove other chemicals from the water like pesticides or herbicides that may be in it as well. They decrease the use of expensive filtration systems.

Duckweed is a fast-growing plant, and most people think its growth is difficult to control. However, people who have used it say the benefits of Duckweed outweigh any irritations they might experience while maintaining their tank.

Frogbit aquarium plant is also an excellent nitrate remover, and it combines with Duckweed in maintaining a healthy tank environment. Frogbit and Duckweed provide a quick solution to the problem by taking up nitrates from nutrient-rich waters before they can cause issues while also using these chemicals as food sources themselves.

You might think that you need to clean your aquarium regularly, but the truth is if it’s full of plants like Frogbit and Duckweed, then there will be less work of water cleaning.

Oxygen Production

Frogbit plant care guideAs you know, Frogbit and Duckweed are floating aquarium plants that can be used to keep your aquarium clean. They also aerate the water in tanks while they’re at it. The more photosynthesis they do, the better. They use the carbon dioxide naturally occurring in water produced by fish to form oxygen which improves water quality for fish who need small amounts of oxygen.

If the production of both these plants gets too low, it will cause stress on the fish, and many health problems will occur. However, if the growth of these plants is maintained, your fish can grow normally and healthy.

Temperature Requirements

Your water temperature should be between 42 and 91 degrees Fahrenheit for optimum growth. If it becomes too cold, the Duckweeds will slow down in their rate of production; but they won’t die because this type of plant can withstand colder conditions than most other plants on earth.

Frogbits also have requirements similar to Duckweeds, and they require a similar temperature for growth. Frogbits basically come from the tropics, so they need the temperature according to that. For Frogbit, you should try to maintain a temperature between 60 to 80 degrees Fahrenheit. Colder temperatures also decrease the growth of Frogbit so take special care of them.

Both varieties of Duckweed and Frogbit are at risk of being devoured by snails. There is a wide variety, which can make it challenging to keep floating plants alive in an aquarium with them present; however, there’s still hope.

Growth Control

Frogbit is a greedy, floating plant that can quickly take over your tank. The Frogbit will eat up all the nutrients in an aquarium if left unchecked, so it’s essential to thin them out regularly, or else you’ll have no fish left.

How much you need to thin the Frogbit entirely depends on the light requirement of the fish and the size of your aquarium. If you have a small aquarium, you may need regular thinning of this plant.  It is very easy to thin their growth. You just have to cut the root of the plant from where they grow.

Similarly, you have to remove the Duckweed every once and a while; otherwise, they can take over the whole tank. In the pond, you should use a skimmer to remove the excess growth of Duckweed in an aquarium. This can be done with the help of the net. Another way to control growth is to increase the water surface agitation. Duckweed doesn’t grow well when its leaves get wet.


Frogbit and Duckweed are both plants that can be grown in an aquarium. Both of these plants are different but are very beneficial for your aquarium or pond. Here is why:

  • Frogbit vs duckweed which one to takeDuckweed and Frogbit are floating aquarium plants, and they beautify the whole tank.
