We have java ferns, rotola colorata, either Taiwan Moss or Christmas Moss, riccia, Amazonian swords and Amazonian frogbits. I guess these plants do not need crazy amount of light.
Another rimless tank I was looking into is a 15 gallon one from CAD Lights and Aquarium, Zen Series. This is not that much bigger than the 10 gallons we have right now so I think I can still use the old equipment.
