For the last few months I have been trying to grow java moss as a carpet, I've attached it to my driftwood and in one tank I have it inside a plant pot, the moss seems to grow but doesn't attach. I really want a carpet in my 12 gallon since I have sand as my substrate which can get messy, so in your opinion what are the best plants that will grow with a 15w standard bulb that came with the tank.
Thanks
