I know plants aren't exactly tank equipment, but I couldn't figure out where to post this - it doesn't seem to fit anywhere. Hmmmm Please move it if need be.
My question is about these growths on the leaf of the java fern. Should I just let this go like this or do these need to be removed and planted or do I need to maneuver that leaf down so the roots have something to attach themselves to? This is the tallest leaf on the plant - it just seems kind of weird to see those roots hanging up there.

With my brown thumb for aquatic plants, any help is appreciated.
