I recently added some Java Fern to my aquarium and have noticed some odd growths on the leaves.
Here is a picture:
Since then, similar nodules have appeared on other leaves. Additionally, some of the nodules appear to be less spherical, as if they were spherical then elongated over time away from the leaf surface. Has anyone ever seen anything like this?
