Try posting this in the Freshwater & Brackish - Planted Tanks section, you might have better luck with what your asking for.
What we need to know though is what kind of lighting you have on the tank now, and if your willing to put co2
, and fertz into the tank. We also need to know if you have any plants in mind.
I'm guessing since it might be your first time with planted tanks, you will want to do a low-tech setup. Low-lighting, no co2
or fertz added. With that in mind, go to this link I post below, it is a list of low-light aquarium plants that would be suitable for a low-tech setup.
