I *think* Micranthemum micranthemoides or "pearl grass." I think this used to be the old nomenclature, though. I refer to it as Hemianthus micranthemoides.Hanzo said:
Dennis, did you mean "salvinia" (where you wrote "sylvania")? :wink:
I have to add that for low-light set-ups, Anubias nana (or "petit" if it's a small tank) is an all-around good one to have - beautiful, and at the same time, indestructible and extremely versatile (can grow it on rock, driftwood, or in the substrate).
