Help identifying small floater

[jonathandowers]

I picked up this mystery floating plant from a LFS. Biggest leave is about 1.5 cm long. Pictured to the right. Any ideas what it could be?

At first, I thought it was the following:
* Giant Duckweed: Leaves are too large.
* Salvinia Minima: Leaves not fuzzy.
* Dwarf Water Lettuce: Leaves look much different.

I would appreciate any thoughts, this is a beautiful floater, and would love to get some more.

frogbits, this looks like a young one..

There seems to be at least three species of frogbits; what's the smallest frogbit species? I believe these are ~3 weeks old.

Popular in Singapore I'd say is the amazon frogbit.

ya, looks like amazon frogbits to me too

Most probably Amazonia frogbits.. When grown in a low light conditions it will be smaller in size.. When grown in high lights they tend to be big...

Yours do not seem to have striations on the leaves. Some forms of the Amazon Frogbit have it, and are very beautiful when viewed from the top. Something like this:

Correct! They are cuter that wAy

From my experience, frogbits remain small with striations under high light. But they propagate insanely (about 3 plantlets attached to the parent plant at a time).

Thanks guys, it did turn out to be frogbit.

Any tips on keeping the roots small? Looks like frogbit has a tendency to root down to the substrate.

Ah yes, mine do that too! I've read some reports saying that the roots stay short when the tank is dosed with fertilisers. No proof behind that though. Personally, I just leave the roots long and remove the older plants as new plants grow.
