Hi there. So I have a few java ferns in my little Fluval Spec aquarium. They are sprouting tons of brown fibers that I believe might be rhizomes from what I've read. They've been present for a few months now and continue to become thicker and thicker. I think I read somewhere that eventually the leaves will turn brown and fall off, and that I can plant the dead leaf with rhizomes to grow even more ferns. However, the leaves don't seem to be dying, just getting hairier and hairier. Anyone got any pointers on how I should manage these things? Should I trim them or just leave them the heck alone? Photo attached... thanks!!
