Anyone have any suggestions for an attractive vivarium ground cover and/or

You're in the right newsgroup! A number of aquarium plants will do well
in such a setting, often as not better than underwater. Dwarf anubias
(A. nana) is up to 2" high, pretty tough-leaved, likes high temp and
very hardy. Bright light not necessary but won't harm. Has a reputation
for growing so slow it drives you mad, but if grown emerged, is much
faster than underwater. I had real good results growing it above water
under the filter return spray. Let it creep up the driftwood, on rocks etc.
Java moss and similar moss-like things should do well. Riccia might need
to have water after all so not so great. Hope it's a good start.
