I'm pretty sure that's not a fern but I stand to be corrected.

This looks to be a floating aquatic with small single leaves. If so, then my guess is Lemna disperma.

What extra info would be required to confirm it?

The other possibility in this family is Spirodela, which has obvious veins in the 'leaves'.
