Oh, looks like
Hygrophila or
Staurogyne.
I'd like to try some though I've given away extra plants from my tank last week so I don't have too many of a single one left. You could pick more than one if they interest you.
This is what I can cut out at this point:
Riccia fluitans
Salivina minima
Rotala rotundifolia
Rotala rotundifolia 'green'
Pogostemon erectum
