I have had plastic plants and rocks in my tank for the past couple years but I am ready to try some live plants. I am trying to figure out some low maintence and easy to care for live plants for my 55g. I do not want it to be over run or anything just some different plants that will grow and thrive easily in a tropical setting without much besides things like ferts. Maybe some grass carpet like substances. Just want to be able to give some fish some places to hide and I am also not sure if it makes a difference if I have gravel or sand but I do have sand.
