It's the same species, immersed and emersed forms, although there may have
been some selection for forms that do best in tropical aquaria.  Ditto
for Lobelia cardinalis which is a streamside plant, native from Florida
to Quebec, and often planted in not-particularly-wet gardens.  I suspect 
aquarium forms are from the southern part of the range, but I could certainly
be wrong.

Btw, there's a yellow-leaved cultivar of L. nummularia.  I've seen it in
plant nurseries but not in aquaria yet.

L. nummularia is often called moneywort as a garden plant.  It can be
quite a spreader, too.  It has pretty yellow flowers.
