In the aquarium hobby, Hydrocotyle is a popular genus of aquatic plants known for their ease of care and versatility. They are often used as foreground or midground plants, and their circular leaves can add a sense of texture and depth to the aquarium. Hydrocotyle plants prefer moderate to high light intensity and nutrient-rich water. They can be planted in the substrate or attached to rocks or wood using fishing line or aquarium-safe glue. Some popular species of Hydrocotyle in the aquarium hobby include Hydrocotyle leucocephala, Hydrocotyle tripartita, and Hydrocotyle verticillata.
