This plant Salvinia (to be precise Salvinia Molesta or Giant Salvinia) is a super easy floating plant. It has 3 forms: Primary, Secondary, Tertiary Forms. I started with Tertiary Form Salvinia, and now have a lot of Primary Form Salvinia, as well as a few Secondary Form Salvinia.
I find that Salvinia is an easy floating plant because:
1) It only requires medium light
2) It has 3 forms and will evolve to the form that is most suited for your tank. The Tertiary Form is usually for outdoor ponds.
3) It is ok with getting a bit wet. Many other floating plants must be completely dry or else they may rot.
4) It has short roots. Hence, there is no need to trim its roots.
5) Easy to remove if you don’t want it. Most of its leaves are linked together. Hence you can remove all the leaves in a few grabs. This is in contrast to duckweed, which is notorious for being hard to remove.
I find that the Primary Form of Giant Salvinia is quite similar to Salvinia Minima, and the Secondary Form of Giant Salvinia is quite similar to Salvinia Natans! Could they be the same species?
Tropica also sells this version of Salvinia which they call it Salvinia auriculata.
