Benefit
Duckweed is actually very beneficial plants and will prove to be useful in our aquarium keeping hobby. Duckweed provide shades for fish to hide under, this is extremely useful for outdoor tanks or ponds where the sun light shines directly into the fish tank or pond. Furthermore, duckweed is capable to reduce the excess nutrient load in the water by absorbing them, this can prevent algae bloom efficiently!
Duckweed is rich in nutrient like protein and vitamin, this make them a great food source for fish which are capable of eating them, for example gold fish and cichilds. Moreover, it can also be use to feed livestock like duck (hence the name duckweed) or chickens.
In Aquarium
Now that you have a brand new impression of this amazing little plants, let's talk about how to keep them in an aquarium.
The first thing you need to take care of is the rapid growth of the duckweed which will be a nuisance if not controlled properly. To control their growth, try limiting their living area by placing them in a plastic basket floating on top of the water. Or you can try using the betta barrack or in-water breeding tank/quarantine tank to place the duckweed. The whole concept is that controlling the duckweed population by limiting their growth space.
Next, duckweed can easily being suck by strong filter or being toppled over by strong current, this will make them unable to grow or reproduce. You will not need to worry about this if you are placing them in a betta barrack or in-water breeding tank/quarantine tank.
When your duckweed grow to a significant amount, try use them as food for your fish like carps, gold fish, cichilds and other plant-eating fish, this will provide your fish with extra nutrients and the fish probably will happily accept it.
