I had a java fern in my tank for approximately five days when it started developing little offshoots. Worried about what they were as I got so many answers online, I separated it and put it into a cup of the same aquarium water and Fluorite substrate, with some Osmocote Plus, and under a grow lamp with the rest of my non-aquatic plants. It has been there for around two weeks and I just realized it is reproducing, but I'm a little hesitant to put it back in my tank. The leaf on which the shoots are developing, and two new leaves have sprung out, is beginning to have small holes forming on it and does not look too hot. Any input on what I should do would be greatly appreciated!
