This sound like what I identify as E. quadricostatus. A few of the Japanese
books seem to call them that also. Check Amano.
If the runners are above or near the top of the substrate, I would go with
Echinodorus. If they are in the subtrate, Sagitarria may be what you have.
E. quadricostatus has nicely root-like roots whereas S. pusilla has roots
more like crypts and you will find lumpy nodes amoug the roots. S. pullia
seems to grow low in bright light and tall in darker areas. E. quad. is
just the opposite.
I've always thought that E. tenellus is more like your front lawn - thin,
short blades, mostly medium to dark green with some reddish leaves. Mine
stays under 2" tall.
