What type of floating plants are these?

[MrGrieves]

These floaters were hitchhikers with a previous plant purchase though I'm not sure what they are. I believe the small one is duckweed but not sure about the larger variety. Can anyone help identify?

Thanks!

Duckweed 🦆🌱and Frogbit 🐸 🦷

Not frogbit, pic below shows frogbit with noticeable stems and very thick, spongy leaves that are always very round.

I think you have regular (Leona minor) and great duckweed (Spirodela polyrhiza) AKA greater duckweed, duckmeat, common duckmeat, plus other common names.

Fix typo on binomial of greater duckweed.

Oh interesting. Yes the underside of some leaves are red/purple which I see is characteristic of this species. Was actually wondering if they were red root floaters. Mine definitely don't have prominent stems. Thanks!

Maybe giant duckweed? Not kidding, it’s a real thing.

Giant Duckweed sounds like the name of a horror movie.
