Aquariums are a popular way to bring beauty and life into the home, and duckweed is one type of plant that is often used to decorate the tanks. But what exactly is duckweed, and is it a good choice for an aquarium? Let’s take a look at the pros and cons of duckweed to help you make the right decision for your tank.

What is Duckweed?

Duckweed is a type of floating aquatic plant that is very tiny and is found naturally in freshwater ponds, marshes and slow-moving streams. Its scientific name is Lemnoideae, and it comes in many different variations. It grows quickly and is a popular choice for aquariums because it is very easy to care for.

Pros of Duckweed

There are several advantages to adding duckweed to an aquarium. For starters, it is an extremely fast-growing plant that can reproduce quickly. It is also low-maintenance, as it does not require any special care or attention. Duckweed is also great for helping to keep the aquarium water clean and clear, as it takes up excess nutrients from the water.

Helps Reduce Algae Growth

Duckweed can also be beneficial in helping to reduce algae growth in the aquarium. Algae can be very unsightly and hard to get rid of, but duckweed can help to naturally keep algae growth under control. It does this by consuming the nutrients that algae needs to grow, so it can help to keep the tank looking clean and clear.

Provides Cover for Fish

Another benefit of duckweed is that it can provide cover for fish in the tank. A lot of fish feel more comfortable and secure when they have something to hide behind. Duckweed can provide this cover, as it grows quickly and easily and can fill up the entire surface of the tank. This can help to reduce stress in fish and make them feel more at home in their tank.

Cons of Duckweed

Although there are several advantages to adding duckweed to an aquarium, there are also some drawbacks. For instance, duckweed can sometimes be difficult to get rid of once it has been added to the tank. It is also important to note that duckweed can use up a lot of the oxygen in the tank, which can be detrimental to the other plants and fish.

Can Take Over the Tank

Another potential downside of duckweed is that it can quickly take over the tank if it is not managed properly. Because it grows so quickly, it can easily spread and cover the entire surface of the tank. This can cause problems for other plants and fish, as the duckweed will block out the light and consume all the nutrients in the water.


Overall, duckweed is a great choice for aquariums, as it is low-maintenance and can help to keep the water clean and clear. However, it is important to keep an eye on the duckweed and make sure it does not take over the tank. As long as it is managed properly, duckweed can be a great addition to any aquarium.
