I decided to try switching my tank over to live plants two weeks ago. The two plants I got then are doing well, so I decided to add some more. Today I bought some java fern and after taking the rubber band off I found that there were four separate plants. I attached the plants to rocks and placed them in the aquariums and that seemed to go well. There were also two pieces of rhizome about an inch long with small roots but no leaves. Is it possible for these to grow and sprout leaves if I attached them to rocks in the aquarium? Thanks in advance.
