Here is a pic of my crappy 12 gallon Eclipse 12 tank. Even with the crappy little single compact flourescent light, the plants are thriving. I actually had to prune that sword alot - maybe 50% of it's foliage because there was almost no water movement due to the plant hogging all the room. I use Flourish Excel and believe that it is the main reason the plants are doing well in that tank.
Well, it's been a bit since I introduced her to my tank and she is doing really well. She routinely pigs out on zuccini and loves her shrimp pellets. Her territory is a chunk of driftwood near the front of the tank, so she's almost alway visible.
