What is Amazon Frogbit?

Amazon Frogbit, scientifically known as Limnobium Laevigatum, is a floating aquatic plant native to the Amazon River Basin in South America. It is a popular choice among aquarium enthusiasts due to its attractive appearance and ease of care. The plant features small, round leaves that float on the water's surface, creating a lush and natural look in your aquarium.

Lighting and Temperature Requirements

Amazon Frogbit thrives in moderate to high lighting conditions. It is recommended to provide your plant with at least 3-4 watts per gallon of light. If you have a low-light aquarium, you can still grow Amazon Frogbit, but it may not reach its full potential. In terms of temperature, this plant prefers a range of 68-82°F (20-28°C), making it suitable for most tropical aquarium setups.

Water Parameters

When it comes to water parameters, Amazon Frogbit is relatively adaptable. It can tolerate a wide range of pH levels, from slightly acidic to slightly alkaline (6.0-7.5). The plant also prefers soft to moderately hard water, with a hardness level of 2-15 dKH. Regular water changes and proper filtration are essential to maintain optimal water quality for your Amazon Frogbit.

Nutrient Requirements

Like all plants, Amazon Frogbit requires certain nutrients to thrive. It primarily obtains nutrients through its roots, which dangle beneath the water's surface. It is recommended to supplement your aquarium with a liquid fertilizer that contains essential nutrients such as nitrogen, phosphorus, and potassium. Additionally, providing a substrate rich in nutrients can also benefit the growth of your Amazon Frogbit.

Propagation and Maintenance

Amazon Frogbit reproduces through vegetative propagation, meaning it can produce new plants from its runners. These runners will eventually develop into daughter plants that can be separated and replanted in your aquarium. Regular pruning is also necessary to prevent overcrowding and ensure healthy growth. Simply remove any excess or decaying leaves to maintain the overall appearance of your Amazon Frogbit.

Benefits of Amazon Frogbit

Aside from its aesthetic appeal, Amazon Frogbit offers several benefits to your aquarium ecosystem. It provides shade and cover for fish, reducing stress and promoting natural behavior. The plant also absorbs excess nutrients, helping to prevent algae growth and maintain water quality. Furthermore, Amazon Frogbit contributes to oxygenation by releasing oxygen into the water during photosynthesis.


In conclusion, Amazon Frogbit (Limnobium Laevigatum) is a beautiful and relatively easy-to-care-for aquatic plant that can enhance the visual appeal of your aquarium. By providing the right lighting, temperature, water parameters, and nutrients, you can ensure the health and vitality of your Amazon Frogbit.
