Common name: dwarf eelgrass
General information
Dwarf Eelgrass, scientifically known as Zostera noltii, is a species of seagrass native to the shallow coastal waters of Europe and North Africa. It is a key species in marine ecosystems, providing habitat and food for a variety of marine life. Dwarf Eelgrass has narrow, ribbon-like leaves that form dense underwater meadows, which are crucial for sediment stabilization and as a nursery ground for many species of fish and invertebrates.

Care
In the aquarium, Zostera noltii requires a substrate that can mimic its natural sandy or muddy habitat. Adequate lighting is essential to facilitate photosynthesis, and the water flow should be moderate to simulate coastal currents. Regular trimming may be necessary to maintain the desired height and density of the meadow.
Symbiosis
Dwarf Eelgrass forms a symbiotic relationship with various organisms. Small invertebrates often seek refuge within its leaves, and it serves as a grazing area for herbivorous fish. Additionally, its root system provides a habitat for beneficial bacteria, which play a role in nutrient cycling within the aquarium ecosystem.
Habitat
Zostera noltii is typically found in intertidal and subtidal zones up to a depth of around 5 meters. It prefers sheltered areas with sandy or muddy substrates, where it forms extensive beds that are vital for coastal protection and biodiversity. Its geographical distribution spans from the North Atlantic coasts of Europe to the Mediterranean and Black Seas, and down to the coasts of North Africa.
