I believe this sounds like Hydrocotyle leucocephala sometimes called
Water Pennywort. Description from "Aquarium Plants Manual":
"leaves alternate, roundish to kidney-shaped with somewhat sinuous
margins. Fine roots on the stem nodes."
The leaves are up to 2" in diameter. Similar in shape to geranium leaves.

I too have experienced a change in my usually lush growth of Hygrophila
Polysperma. I introduced a new aqua-plant light (strong bluish spectra)
but maybe it's the water.
BTW. anyone know the secret of Ludwigia repens? It is a beautiful plant
but I have not had any success. I think it needs a very rich substrate.
I'm interested to hear what you all are using for substrates especially
anyone who has had success with long-term Aponogetons (2yrs +). I think
I will redo my 49 gal. substrate this year. Gravel + fertilizer is not
enough, I suspect.
Anyone propagating Aponogeton Madagascariensis out there? Or any
