Found in its natural habitat growing attached to roots and rocks, it can grow in both fully and partially submerged environs.
Pro Tips
This plant is easy to propagate by splitting the horizontal rhizome. Sometimes plantlets start to grow on the leaf edges and if you leave these intact long enough, you'll get a plant you can detatch and grow. Note that the black spots under the leaves are sporangia (reproductive organs) and not signs of disease as many believe.
If it is planted in the bottom, do not cover the rhizome because it will rot.
