Sea grasses are the most productive group of marine plants in the ocean, forming extensive meadows in shallow, nutrient-rich environments. There are approximately 60 known species that occur in tropical and sub-tropical waters worldwide. Sea grasses provide shelter and habitat for juvenile fish and invertebrates, and effectively filter near-shore habitats of nutrients, creating an oxygen rich environment. They are also an important component of the coral reef by filtering and buffering the flow of water and trapping sediments before they reach delicate corals. There are currently about 7 species available to the hobbyist for culture in the aquarium today. Most species require deep sand beds (6" or more) as their root systems are extensive and demand for organic nutrients high. A few of the pioneer species, such as Halophila and Halodule, can be planted in shallower substrates as they are relatively less demanding when compared to Thalassia.
