Hello TFF. Have some Dwarf Water Lettuce going in this 50 gallon tank. It's a perfect plant for hiding fry from adult fish and does a good job of filtering the nitrogen from the tank water. Add to that some Chinese Evergreen and you have extra clean tank water. The water lettuce is such a fast growing plant and needs only florescent light. I use a two bulb strip light typically no more than 30 to 40 watts per bulb and 6500K in the the outdoor daylight range, or whatever you can get at the local hardware store. The only problem with the Dwarf Water Lettuce is that it grows fast and really outgrows the name "dwarf". Here's a photo of the two plants in the 50 gallon tank.
