🌱 What is Microsorum?
Microsorum is a genus of ferns, of which Microsorum pteropus is the most common aquarium inhabitant. What makes this plant unique is that it grows from a rhizome, which should not be planted in the ground. The plant draws most of its nutrients from the water through its leaves and roots, which attach to surfaces.
