~ one of the prettiest tanks I ever had was a little ten gallon
fresh water planted tank with nothing more than a regular fourescent hood that came with it. I kept Amazon sword's alive, anubias is great, and java fern (that was attatched to some driftwood) My tank also got a little bit of sunlight from a window for a few hours a day. The tank is shallow, and doesn't need a super strong light. Go for it. Put something in, and see what thrives... you may be surprised. Just remember, if you have a lot of duckweed on top (which does need a lot of light) it cuts down on the light that reaches the bottom of the tank. Surprisingly, I got some tiny, ugly, cheap, little brown plant bulbs (in a bag) from the fish section of Walmart LOL (I was wandering around looking) and I thought what the heck? I dropped them into my ten gallon tank, and they ended up growing and becoming more beautiful than anything I bought at the fish store.
