Amazon Frogbit (Limnobium laevigatum) is a floating plant that is equally suitable for both open aquariums and aquariums with a cover. Amazon Frogbit has large bright green leaves and long finely branched roots, the Frogbit not only provides excellent protection for young fish but is also an eye-catcher in any aquarium. Many well-known ornamental fish such as barbs, tetras, and egg-laying toothcarps love Frogbit as an ideal spawning substrate. Here the eggs can develop in peace, and the young fry are protected from predators.
As far as floating plants go, Amazon Frogbit is an excellent plant for both beginner and more experienced aquarists. Frogbit's main requirement is sufficient light to grow optimally, which generally isn't difficult to achieve with floating plants.
Amazon Frogbit is quite fast-growing. As a result, Frogbit consumes excess nutrients and prevents excessive algae development. Furthermore, the shade provided by the large leaves of the Amazon Frogbit contributes considerably to keeping algae in the aquarium in check. Although Frogbit reproduces quite rapidly through the numerous offshoots that appear, excess specimens of Frogbit can be easily removed.
Frogbit is very tolerant of water temperature and grows well in the range of 62 to even 95°F. Soft to medium-hard water is favorable. Good growth is supported by intensive lighting and high humidity. When the water level is low, Amazon Frogbit develops particularly well, because the roots are able to reach the substrate. Under favorable conditions, Frogbit multiplies quite quickly and form a dense floating plant cover, the extent of which can be regulated very easily by collecting excess plants.
