Amazon Frogbit (Limnobium laevigatum)

Amazon Frogbit floats rosettes of round, lily-pad leaves with long feathery roots that shelter fry and shrimp while stripping nutrients from the water column. It dims the tank below — a feature for low-light plants and shy fish, a tradeoff above carpets.

Propagation

Daughter plants bud off on short runners; separate them or scoop out excess by the handful.

Frequently asked questions

Why is my Frogbit rotting from the top?

Frogbit dies when its leaf tops stay wet — usually from filter splash, condensation drip, or being pushed under by strong flow. Corral it with airline tubing or a floating ring in the calmest corner and keep the lid from dripping on it.

Will Frogbit steal light from my other plants?

Left unthinned, yes — a full canopy can cut light below it dramatically. Keep it to a fixed zone with a floating corral and remove a portion weekly; the shade it casts is also a legitimate tool for algae control and light-shy fish.
