I picked up several house plants at a nursery(garden center) center that are doing great under 3x 13 watt cfl bulbs (6500k) in reflectors that are 12" or less above the plants.
Pothos varigated - monster vine, mostly green with some lighter splothces
Fittonia albivenis - green with vibrant white veins
Tradescantia zebrine (aka "wonder jew") - purple with thick banded striped
4/16 (originally most of the pothos I bought was in a planter, but moved it into riparium)
The tradescantia actually grows faster than the pothos and needs trimmed ever month to keep it form getting to heavy and sinking into the water. Trimmings just get slapped back into HOB or riparium planters, grow roots out the cut end, and keep on growing.
Pothos will get monster roots over time but you can trim them or stuffed them down into the substrate when they get long enough.
The Fittonia albivenis I really live, though its the slowest growing of the three but its low and dense so good for hiding the media the planters are planted in.
I also tried maidenhair fern but it didn't like the setup.
Btw non of these like having wet leaves (submerged) so keep the leaves above the waterline if you try them.
I actually just re-did the riparium and got some more riparium specific plants and more planters, but still have all the original house plants (except the fern)
