I am new to plants as well I and just purchased two java ferns. When I got home I was able to pull 7 starts from those two plants and replant them tied to some rocks. If you are buying Java ferns the new starts will be growing off of the leaves of the plants. If you see some red fuzzing stringy stuff coming from the leaves those are baby plants that you can remove and re plant. They are a low light plant and seem to be thriving in my very low light set up. I have two small anubias and a sword that are doing well also. (I only have a single 32 watt light for a 75g tank.)
