How to keep floating plants in aquarium

Floating plants are a great addition to the home aquarium. The first few times we tried to keep floating plants, it all failed. Water lettuce, frogbit, and red root floater all melted away and died within days.

After multiple tries, we think that we have figured out the tricks to keep floating plants in the aquarium! The YouTube video below summarizes 8 essential tips for keeping floating plants alive and thriving in the home aquarium.

For beginners we recommend Salvinia, or water spangles, as the first starting floating plant. It is also easy to remove, as a great contrast to duckweed.

I think Salvinia is one of the easiest floating plant to keep in an aquarium. It has 3 forms Primary form, Secondary form, and Tertiary form and will adopt the most suitable form for whatever conditions is in your aquarium. (The photos shown below are Primary form. Initially, when I bought it, it was in Tertiary form.)
