Halodule is a genus of seagrasses in the family Cymodoceaceae, commonly known as Shoal Grass. These marine plants are important in saltwater ecosystems, providing habitat and food for a variety of marine life. In the aquarium, Halodule species can be used to create a natural-looking seabed and can be beneficial for species that require seagrass for their well-being. They require moderate lighting and a substrate rich in nutrients to thrive. While not commonly kept in home aquariums, they can be a unique addition for hobbyists looking to replicate a natural marine environment.
