I can say surely there is duckweed (lemna minor) and salvinia (salvinia minima).

Duckweed is the tiny greenish-limey colored star-shaped plant. It is a great floater, but keep in mind it spreads super fast. Salvinia is amazing! It spreads moderately but doesn't take over as quickly as duckweed. Salvinia is the plant with hairy/fuzzy spores on top. Salvinia plants are also called "floating ferns" or "water-spangles." 🙂 

I can't tell based on the picture entirely, but there may also be amazon frogbit (limnobium laevigatum) in there. Here is a pic of frogbit for you to compare on your own. Hope this helps!

Thanks, i had suspected frogbit from pictures i had seen. It just looked to small, perhaps just juvenile plants.

Thank you

No frogbit in @Jerr’s pic, but @clownbaby’s pic is definitely frogbit.  It has those skinny but strong stems, separated, very circular leaves, and smooth surface even when the plant is tiny.  The stems are much more substantial than red root floaters or Salvinia for instance.  The close together leaves look like duckweed (Lemna minor) for the tiny ones and likely greater duckweed (Spirodela polyrhiza) for the medium ones along with a Salvinia for the largest, textured ones but I’m not sure which species.  It might be Salvinia minima?

Yep! I pulled the image of frogbit from the internet so @Jerr could compare in-person, but I personally do not think there is any frogbit in the mix of those floaters... The textured ones (fuzzy / hairy looking leaves) definitely seem like salvinia minima, but there are so many salvinia species... who knows haha  !!! And thank you for clarifying on the duckweed! It is hard for me to personally distinguish between different duckweed species, but I will say it seems like you are right and know your stuff :]

Thanks for the info! (and the learning continues)
