Aquatic Ferns

Aquatic ferns are some of the easiest plants to grow,  they don't need substrate, they thrive in low light, and they're almost impossible to kill. Just attach them to driftwood or rock and let them do their thing. Java fern and bolbitis are staples in my own tanks because they're low-maintenance and look great once they fill in. Perfect for beginners or anyone who wants a planted tank without the fuss.
