Bolbitis is a genus of aquatic ferns in the family Lomariopsidaceae. These ferns are distributed in tropical and subtropical regions worldwide and are commonly known as water ferns or creeping ferns.
Bolbitis ferns are found in a variety of aquatic habitats, including slow-moving streams, ponds, and swamps. They are often rooted in the substrate, but they can also be found attached to rocks or other aquatic surfaces. Bolbitis ferns have elongated, narrow leaves that grow in a rosette or tufted pattern, and their fronds can range in size from a few centimeters to over a meter in length.
In the aquarium hobby, Bolbitis ferns are highly valued for their unique appearance and their ease of care. They are often used as midground or background plants, and their long, flowing fronds create a striking contrast with other aquarium plants. Bolbitis ferns are relatively tolerant of a wide range of water parameters, but they prefer moderate to high light intensity and nutrient-rich water. They can be propagated by dividing the rhizomes or by planting small plantlets that grow from the fronds.
