A neat addition to any tank where you would like floaters but want more of a dynamic look than regular old duckweed. The leaf is larger than common duckweed and grows in clusters of 3-4 leaves. The leaves of mature plants are flat, intensely green, and very shiny.

Spirodela polyrrhiza grows great with little intervention or care and has a cool habit of the undersides turning reddish or purplish. 

Fun fact: Spirodela polyrrhiza is in the same family as common houseplants Anthurium and Alocasia!

I will provide a volume of floaters in enough quantity to fill a sorting tray similar to the one in the last posted photo. I will do my very best to remove any duckweed, but I can't guarantee it 100%.

This plant is not too picky on temperature or water chemistry, but is coming from a tank that runs around 76°-78°F and has a pH of 6.8-7.0 with hard Minneapolis tap water.
