American Frogbit Floating Aquarium Plant
American Frogbit Floating Aquarium Plant
American Frogbit (Limnobium spongia) is a hardy and attractive floating aquarium plant known for its round, glossy green leaves and long trailing roots. Native to North America, this freshwater plant is a beautiful and functional choice for planted aquariums, shrimp tanks, fry grow-out tanks, and peaceful community aquariums.
As a floating plant, American Frogbit rests on the water’s surface and helps create a more natural aquarium environment. Its roots provide excellent cover for shrimp, fry, and small fish, while the floating leaves offer shade and help reduce excess light in the aquarium. Frogbit can also help compete with algae by absorbing extra nutrients from the water column.
This fast-growing aquarium plant is easy to care for and does not require CO2, making it a great choice for beginners and experienced aquascapers alike. With regular thinning, American Frogbit can be managed easily while still providing natural beauty, movement, and shelter at the surface of the tank.

Tank Setup
American Frogbit does best in aquariums with gentle water movement. Strong surface agitation can damage the leaves or prevent the plant from spreading properly. It should be kept away from areas with heavy splashing, strong filter outflow, or constantly wet leaf tops.
For best results, provide stable water conditions, moderate lighting, and occasional liquid fertilizer. Regular trimming or thinning is recommended so the plant does not completely cover the aquarium surface and block light from plants below.
