Hello! I have an established tank that I'd like to add plants to. Although I am an avid gardener, I did not have luck with aquarium plants when I tried it several years ago. I just redid my tank...it now homes angelfish, tetras and 2 bolivian rams. As much as I'd love to really love to go crazy with plants, I just don't have time to learn about them right now. Are there any REALLY easy plants for aquariums? My lighting is just a regular 40watt aquarium bulb. (I rarely turn it on because there is enough natural light in the room for the fish, however, I would be willing to leave it on as needed for plants). Any advice is appreciated. Lisa
