Here are five benefits of duckweed in your aquarium: 1. *Natural Food Source*: Duckweed is a great food source for herbivorous fish, such as goldfish, koi, and tilapia. It's high in protein and fiber, making it a nutritious addition to their diet. 2. *Oxygenation*: Duckweed helps increase oxygen levels in the water, which benefits all aquatic life. It undergoes photosynthesis, releasing oxygen as a byproduct. 3. *Water Purification*: Duckweed absorbs excess nutrients, such as nitrogen and phosphorus, from the water, helping maintain water quality and prevent algae blooms. 4. *Shelter and Habitat*: Duckweed provides a sheltered environment for small fish and invertebrates, offering protection from predators and strong currents. 5. *Aesthetics*: Duckweed adds a beautiful, lush green carpet to the surface of your aquarium, creating a natural and visually appealing atmosphere. Remember to maintain proper care and balance when introducing duckweed to your aquarium, as it can proliferate quickly!
